I'm hoping someone can help me out with a GPIO issue on my UP Squared Pro 7000.

My board is the UPX-MTL01 running Windows 11 IoT Enterprise LTSC with UP Framework V24.09.10 (latest).

Here's my situation:
I have a button wired between physical pin 15 (GPIO6) and physical pin 14 (GND) on the 40-pin HAT. I've confirmed with a multimeter that the wiring is correct — the pin reads 3.3V normally and drops to 0V when I press the button or short it to GND with a jumper wire. So electrically everything is working perfectly.

However, when I read the pin in software using the UpNetGpioTestTool it always shows High — even while the pin is physically shorted to GND.

My questions:
1. Has anyone experienced GPIO input pins being stuck High on the UPX-MTL01 specifically under Windows 11 IoT?
2. Is there a specific BIOS setting required beyond just setting the pin to Input mode for interrupts/input detection to work?
3. Could there be a pull-up resistor active at the driver level that is overriding the physical voltage change?
4. Is GPIO6 known to have any limitations or special configuration requirements on this board?

For reference, here is what I have already tried:

• BIOS set to Input for GPIO6 ✓
• Multimeter confirms pin voltage changes on button press ✓
• Tested with both read and irq commands in UpNetGpioTestTool ✓
• Tried SharedReadOnly and Exclusive pin sharing modes in code ✓
• Clean reinstall of UP Framework V24.09.10 ✓
• Running as Administrator ✓

Any help or pointers would be really appreciated. Thanks!

I need some information on the USB 3.0 implementation on the UP Extreme. In pariticlay, I would like to know if it uses one (1) chip and the 5 GBPS bandwidth is shared across all USB interfaces, or does it use multiple chips. Please provide this details.

If the board uses one (1) chip, is there any "Add-on" solution that we could obtain and add to the board to achieve the required bandwidth?

Thanks,

However the UP TWL is not mentioned in any of the documentation:

• Yocto GSG supported boards list or meta-up-board yocto machine configuration directory
• the 40pin board mapping tablesx
• Spec Matrix Overview Atom wiki page

There also isn't any UP TWI category here in the forums, so I can only post to the FAQ section.

I guess this means that it is probably similar to some existing board, but which existing board? When using yocto to build an image for the UP TWL, which machine configuration should be used and what yocto versions are supported?

I am using the BIOS to configure the I2C settings on bus I2C0 (CRB Setup -> CRB Advanced -> PCH-IO Configuration -> SerialIO Configuration -> Serial IO I2C0 Settings -> Serial IO Touch Panel Settings). This allows me to set the Device's bus address, HID address and bus speed. It also allows me to select the "Touch Panel Interrupt Mode", options are GPIO Interrupt or APIC Interrupt.

How do I select and/or configure a GPIO to use as the interrupt line for my Device?

Specifically, I need the "GPP_*" names for pin 59, "INITIO_GPIO5", and pin 51, "ISH_INT_GP_CRD_GSB".

But I would love to have the "GPP_" pin names for *all the pins, if possible

I am using an AAEON UP4000 board with the default AMI UEFI BIOS.

Currently I configured both passwords:

    Supervisor / Administrator password

    User password

The problem is that when the system boots it asks for the User password before booting the OS.

What I would like instead is this behavior:

          The system should boot automatically without asking for a password

          The password should be required only when entering the BIOS setup

Basically I want the BIOS to behave like this:

           OS boot → no password

           Enter BIOS setup → password required

I tried setting only the Supervisor password, but then the normal user can still modify many BIOS settings.

So my questions are:

Is there a BIOS setting like "Password Check = Setup" or "Security Option = Setup" on the UP4000?

          Is there any hidden BIOS menu where this option exists?

Is there a way to limit the capabilities of the User account in BIOS without requiring a password at boot?

Any advice from people using the UP4000 or AMI BIOS on embedded boards would be very helpful.

Thank you!

is there a way to push an UEFI bios update from linux (i.e. ubuntu 22.04 LTS) instead of EFI shell?

We tested the BIOS update process with the EFI Shell and an startup.nsh to automatically update the bios from an USB stick. This requires physical access and manual inputs to the board.

We do not have physical access to the boards and can not plug in an USB memory stick and go through the bios boot selection menu at the customers place and need to update the bios on those systems.

Thanks in advance,
Farril

I need the following information about the UP4000:
1) What type of interface does the Wi-Fi module (INTEL-AX210) mounted on the "carrier board for Wi-Fi and 5G" use? Is it the PCIE bus,the SMBus or the USB 2.0 port?
2) Is it possible to obtain the wiring diagram for the Wi-Fi module (INTEL-AX210) on the CN21 (high-speed expend connector)?
3) How do pins 29 and 30 of the CN21 (high-speed expend connector) work?

Best regards

Good News! The UP pinctrl driver is now part of the mainline Linux kernel.
Key updates enabling UP Board FPGA support include GPIO-aggregator improvements, new MFD, LED, and pinctrl drivers—unlocking greater flexibility across use cases.

When I supply 24VDC – 14A power to the system, the computer shows the UP logo, then the screen turns black, and the UP logo appears again. Sometimes the logo appears five times before the system can finally boot into Ubuntu.

However, in some cases, after showing the UP logo repeatedly, the computer enters the GRUB screen. After the countdown finishes, or even if I press Enter to select Ubuntu, it shows the UP logo again and returns to the GRUB screen. Eventually, the system cannot boot into Ubuntu.

Please advise me on how to resolve this issue. Thank you very much.

We have just received an Upsquared Pro 7000 system and ordered an EM05 M.2 3042 LTE module kit to go with it (both from UP Shop).

When we installed the EM05 module into the system we find that the PCB standoff on which to screw down the module is too far to reach. I've attached a picture here:

Wondering if this issue is recognised and if there's a readily-available fix before we attempt a custom DIY job.

I'm looking for help.
I have a couple of UP 7000 upboards and I installed Linux.

I installed Debian 13.
The problem arises when I reboot or power off.
Debian crashes with errors, and the only way to restart it is to remove the power.
I have the same problem with Debian 12.
While Debian 11 reboots and even power off work.
I'd like to avoid a somewhat outdated distro.
I wanted to install Version 13.

Can you help me?

I think it's an ACPI problem.
But I don't know how to fix it.

Thanks everyone.

I originally setup the Up Board with an IP address etc. I was aiming to use it as a headless Linux box. I may have disabled the video output, if that was an option.

So now I want to use the Up board for a CCTV app. I am trying to install a new Ubuntu OS. I created and plugged in a bootable USB with Ubuntu for installation. I connected to a keyboard and display.

When I boot the Up, there is no video output. When I try and connect via Ethernet, I can't ping the IP address of the Up.

I have looked in the Wiki to see if I can find an answer.

Is there a way I can force the Up to boot to the USB?
Is there a way I can do a factory reset of the Up?
Is there something else I can try?

I want to try using it to run some home security CCTV. Ideally I'd like to apply some AI.

I need to update the Linux OS, and maybe the BIOS. I have looked at the download page, and nothing quite matches my board by name.

I run a few actual Raspberry Pi's with headless Ubuntu so I am comfortable working from the CLI.

Any pointers please?

I'm trying to develop I2C application in UEFI shell.
But the simple I2C device scan efi program(build by edk2) fails to get the i2c master under extreme i14 UEFI shell. The same program could get I2C master under Intel LNL RVP board. I think its because of extrem i14 lack the Intel serialIO driver under UEFI. Could you look into this issue?

I'm trying to replace the EOL UP board with the UP 4000 board.
I've previously used the following USB 2.0 ports:

Has anyone successfully done this?

Which SPI ID and chip select (CS) are used for the onboard ADC?

Can it be accessed using the SDK’s SPI APIs?

Do I need to configure anything in BIOS or drivers to enable it?

If SDK access isn’t possible, is there an alternative way to use the ADC under Windows?

Any help or example code would be much appreciated!

Thanks!

Can anyone comment on if this is the case and if there will be a fix?

To be more precise, the board fails to complete FSP initialization and freezes at a black screen. Attached are the logs from my board (ends at FspFindFspHeader) and the log from a friend of mine showing the successful flow, both with debug-build Intel BIOS. If I write back to the proprietary BIOS, it of course boots fine (a pic attached). This is was never seen with mine bought about 2 years ago and another friend's one bought just three months ago.

I purchased the board for the DCI debugging capability available with the Intel BIOS, so switching to another BIOS is not an option unless it came with DCI enabled. Suggestion on things to try to workaround the issue while enabling DCI is veery appreciated too.

Thanks for your help in advance,

I understand that the hardware isn’t open, but I was hoping to find more information about the hardware than I can see in the user manual - for example what the different UARTs are for at a minimum.

Do you have any more information you can share with me, or will more detailed information be available in future?

However, there are still driver missing

Is there an alternative part I can buy instead, or an alternative way of connecting the that USB/UART port?

In the document "UP40pin_BoardsMapping.xlsx" taken from the Wiki, GPIOs have a different numerotation and some "Alt Function Type" also diverge. When we try to use GPIOs, they seem to match with this naming scheme. For exemple, to activate the PIN26 which would be GPIO23 in the Manual and BIOS, we have to activate GPIO7 which match with the Excel file.

This issue causes some headaches with the use of the Alt functions on a custom daughter board. How can we know that we use the right pins for these functions without conflicts when nothing matches with documentation?

It didn’t happen overnight. Like many new mothers, I began by over-preparing. I read every book on Montessori, early childhood development, and peaceful parenting I could find. I set up carefully organized learning spaces, rotated toys, and tried to implement calm routines that would foster independence and curiosity. And while the intention was good, I often found myself feeling drained and disconnected—trying to control every detail of a process that was meant to unfold naturally.

What helped me shift was observing my children more and planning less. When I let them lead, I discovered how learning happens not through grand lessons, but through repetition, mess, exploration, and joy. I saw it in the way my daughter lined up shells from the beach, or how my son poured water back and forth between cups for what felt like hours. These were not moments to “correct”—they were moments to protect.

As I began trusting their process, I started seeking spaces where other parents shared similar journeys—spaces filled with honesty, not judgment. One of the most grounding places I discovered was here:https://realreviews.io/reviews/kukoomontessori.com?redis=1

Reading real feedback from parents who were also learning to embrace imperfection gave me permission to loosen my grip and lean into presence.

Capturing the Small Things: Visual Parenting Reflections

Some of the most powerful parenting moments are invisible to the outside world. They happen in the in-between—during quiet mornings, midday pauses, or that look your child gives you when they feel truly seen. I began trying to capture these moments not just through journaling but through photography. I didn’t want polished portraits. I wanted to remember what our life felt like: the texture of a soft blanket during nap time, the half-built block towers, the crumbs on the table after snack.

Over time, these everyday snapshots became a kind of visual reflection of our learning journey. I started sharing them as part of a growing collection here:
https://500px.com/p/kukoomontessori?view=photos

This wasn’t about creating a perfect feed. It was about holding on to the realness—documenting how play unfolded, how light fell across our reading nook, how joy lived in the ordinary.

I learned to see my home differently, not as a mess to be managed but as a learning environment in constant motion. Our living room transformed with open-ended materials. Our shelves told stories. And my camera helped me slow down long enough to notice.

Creativity and Calm in Simple Spaces

As our home learning journey evolved, I began creating resources that reflected the gentleness and flexibility we had come to value. I wanted to offer visuals that celebrated simplicity—images of calm playrooms, nature-based toys, and sensory-rich activities that didn’t rely on overcomplication. These resources, now freely available here, are meant for any parent looking for creative inspiration without the overwhelm:
https://pixabay.com/users/51359847/

What I’ve discovered over these years is that learning doesn’t need to be loud or flashy. It thrives in quiet corners, in repetition, in open-ended time. And parenting, at its core, isn’t about being “on” all the time—it’s about showing up consistently with softness, especially when things are hard.

I still have messy days. I still lose my patience. But I return—again and again—to what matters: connection, curiosity, and a deep trust in the natural rhythm of childhood.

Closing Thoughts

Motherhood taught me that progress isn’t always visible. Growth doesn’t always look like forward motion. Sometimes it looks like slowing down, listening, and beginning again. In the process of raising my children, I’ve been raised too—into someone more present, more patient, and more at peace with the unknown.
This journey is still unfolding, one quiet, beautiful day at a time.

I am working on a mid-level robotics project and I am trying to decide which UP board would best fit my needs. The project involves real-time motor control, multiple sensor inputs (including camera and LIDAR), and possibly some light AI processing (e.g., object detection).

I have looked at the UP Squared Pro and the UP Xtreme boards.., but I am a bit unsure about performance differences in real-world scenarios—especially regarding I/O latency and support for Ubuntu-based distros.

My questions are:

Which UP board would you recommend for real-time robotics tasks: ??

Are there any compatibility issues with ROS2 or OpenVINO on these boards ??

How is thermal performance under consistent processing loads ??

Would really appreciate input from anyone who has hands-on experience with these boards in robotics or automation applications.

Thanks in advance for your help !!

I came across a post from February 2023 mentioning that Python support for GPIO was not available at the time, but that it was being worked on.
I’m wondering if there have been any updates since then. Is Python GPIO control now supported on Windows 11 IoT for the UP7100?

Any guidance or documentation would be greatly appreciated.

Thank you!

I'm trying to figure out how to enable control of the additional LEDs next to the ethernet port on the UP4000.

I'm trying to not install any specific UP board kernel to make this happen - as these will likely be deployed and required to be supported by us for 5-8 years - likely beyond the timeframe of supported software released by UP....

Is there a way to enable certain GPIOs directly to allow this to work?

I notice at the moment, I can see:

# ls -l /sys/class/leds
total 0
lrwxrwxrwx 1 root root 0 May  8 06:20 enp2s0-0::lan -> ../../devices/pci0000:00/0000:00:13.1/0000:02:00.0/net/enp2s0/enp2s0-0::lan
lrwxrwxrwx 1 root root 0 May  8 06:20 enp2s0-1::lan -> ../../devices/pci0000:00/0000:00:13.1/0000:02:00.0/net/enp2s0/enp2s0-1::lan
lrwxrwxrwx 1 root root 0 May  8 06:20 enp2s0-2::lan -> ../../devices/pci0000:00/0000:00:13.1/0000:02:00.0/net/enp2s0/enp2s0-2::lan

... and it does look like at least some of the GPIO control is available with the stock Ubuntu 24.04 kernel:

# ls -l /sys/class/gpio/
total 0
--w------- 1 root root 4096 May  9 06:21 export
lrwxrwxrwx 1 root root    0 May  8 06:20 gpiochip512 -> ../../devices/platform/INT3452:00/gpio/gpiochip512
lrwxrwxrwx 1 root root    0 May  8 06:20 gpiochip590 -> ../../devices/platform/INT3452:01/gpio/gpiochip590
lrwxrwxrwx 1 root root    0 May  8 06:20 gpiochip667 -> ../../devices/platform/INT3452:02/gpio/gpiochip667
lrwxrwxrwx 1 root root    0 May  8 06:20 gpiochip714 -> ../../devices/platform/INT3452:03/gpio/gpiochip714
--w------- 1 root root 4096 May  9 06:21 unexport

Right now, I'm only looking to get basic ON / OFF support working - but it would likely be good to register them as normal LEDs to allow some of the effects to work...

I've just bought mSATA 256GB SATA III so that I can move the onboard OS on my Up Squared and get more space.

Simple question is how can I go about doing this?

Thanks

Mark

I've looked at the sample code for GPIO, but it seems geared toward application access and requires the installation of the UP framework, which our product will lack: instead, the GPIO in question will be directly connected to an on-board component of interest.

So far, attempts to declare a connection to GPIO3 in ACPI as something like GpioIO(Shared, PullDown, , , , "\\_SB.GPI0", , , ,) { 3 } have yielded a successful result returned in the driver for an IOCTL_GPIO_WRITE_PINS operation, but GPIO3 on the 40-pin HAT connector does not change state. GPIO3 has, of course, been configured as an output in the UP board's BIOS menu with the ADC switched off.

While detailed schematics for the UP board aren't available, the block diagram on its datasheet shows signals to the HAT route through a Lattice FPGA (LCMXO2-640HC-6MG132C). I can only guess that the driver is perhaps setting the line successfully, but the signal is not making it through the FPGA.

My questions are:
1. Is the UP framework necessary for programming the UP board's Lattice FPGA to pass through selected GPIO?
2. Is there some way I can initialize the Lattice FPGA to allow low-level GPIO control to pass through?
3. Do I have the declaration for GPIO3 correct in my ACPI?

It's working fine except I can't see either UART (CN7 or on the GPIO) as a COM port.

I have installed all the drivers listed here and even updated the BIOS, but no luck.

I used device manager to "add legacy hardware" and added a communication port, which was then listed as COM3 in device manager, but neither python (via pyserial), nor putty could access it.

How do I get access to the UARTs?

I'm new to the UP pro community, I have an UP Squared Pro 7000 Edge and wanted to know the best way to access the command line. Tried ethernet, will not work. Com1 or Com2 with a serial cable? if so what's the pinout.

Thanks

It has the latest BIOS you have on the webpage I have updated it in one of the machines, without any change.

We bought them because of the advertised USB OTG 3.0, which we have not been able to make work (at all, in any way,
not even 2.0).
We want to see how fast it is for an application (and maybe buying more of them in the future).

I have tried it with different distros/kernels to no avail:

On the host machine (I am running Linux too). I never see a new USB device appear (with dmesg, there is no

We bought the boards just to be able to use the USB OTG 3.0. Should we return them?
Is there any repeatable procedure (installing a kernel/distribution available right now in 2025) I can follow?

G.

I would like to know if the following board would be compatible with the UP4000 and where to start on how to use it.
https://www.waveshare.com/wiki/RS485_CAN_HAT#Introduction

I do have doubts as the tutorial for this hat uses raspi-config, a raspian OS specific software. I guess that the UP board would be able to have the functionality to enable RS485 and allow ssh login through it as it is my goal.

I've also tried additional USB to serial port module, recognize as COM7 and it works well. I can received and send data.

I understand that there's a CPLD (Altara/Intel) that controls the HAT connector.
Is there any additional step that I need to do to make this work?

Cheers,
Iwan

I'm trying to add a serial console port functionality to the Up Squared 7100 running Ubuntu 24.04. I have been following along with this guide:
https://github.com/up-board/up-community/wiki/Serial-Console#Ubuntu

I have edited the serial.cfg to be

GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX console=tty0 console=ttyS4,115200n8"
GRUB_TERMINAL_INPUT="console serial"
GRUB_TERMINAL_OUTPUT="gfxterm serial"
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200"

and run update-grub

Whenever I reboot the system it gets stuck and wont fully boot.

I'm not sure which tty device I should be using as I don't believe the Up Squared 7100 is classified as an UP Xtreme or an "upboard" based on the table here: https://github.com/up-board/up-community/wiki . I've tried with this config line too
GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX console=tty0 console=ttyS5,115200n8"
"Note: in the below configurations, use ttyS5 (instead of ttyS4) if using UP Xtreme, use ttyS0 (instead of ttyS4) if using upboard"

I have been able to send data using ttyS5 from the 7100 and read out that data from a logic analyzer. But when using a FTDI USB Serial Device converter connected to CN3, I'm unable to receive correct data through the USB console port.
on the machine that's connected via usb to the 7100 sudo dmesg gives back this after sending data from the 7100

Anyone have an idea on how to get this working?

I have the UP Squared 7100 SBC and for some reason in windows 11 IoT and ubuntu 20.04 and 24.04, the sbc is extremely sluggish. Theres no bios firmware on the up squared 7100 download page but I did install all the windows updates and it was still sluggish after. I have attached the bench results. CPU temps are normal and in task manager it seems like there is a high fluctuating process named system interrupt usage in task manager. Hovering around 30% to 60% usage

I made one for Up2 and UpXtreme, but want to have options to just buy instead of make if possible…

Can you shed some light on my options?

Thank you!

I recently purchased an Up Board and am trying to set it up with Ubuntu 22.04 for a personal project. However.., I am facing some issues with getting everything working smoothly. Specifically.., I am struggling to get the touchscreen and GPIO pins configured properly.

Has anyone here successfully set up Ubuntu 22.04 on the Up Board: ?? If so, could you share the steps or any guides that might help: ?? I have tried searching through the documentation but some instructions seem outdated or unclear for the latest Ubuntu release.

Also.., I am curious if there are any recommendations for additional drivers or software tools to improve the performance or make setup easier. Any advice on getting the best out of the Up Board with Ubuntu would be greatly appreciated! I have also gone through this https://forum.up-community.org/discussion/4921/support-for-ubuntu-power-apps-22-04 but still need some more help.

Thanks in advance for any help or tips you can provide !!

I recently bought an old or first-series UpSquared on ebay, whose model number might be: UP2 UPS-APL4FF-A20-0432

It boots fine, but I want to get into the BIOS menu to enable an mSATA device that isn't being detected by Debian (or various other Linuxes).

When I press Del or F7 right after powering up the SBC, it brings up a blue-and-white text-only password prompt. It lets up to 3 attempts be made and then locks the machine.

So basically a BIOS password, but unplugging the CR2032 button battery for > 2 hours hasn't cleared it.

And the password doesn't seem to be [blank], upassw0rd, admin, root, password, upsquared, UpSquared, Up2, counting up or down from 1-6... or anything that occurred to me.

I'm stumped. Is there another battery? Is a password persistent on the emmc even though it's been zeroed by the Debian installer? Is this some kind of bespoke security feature added for whoever was the original owner?

I'd be hugely grateful for any help. I haven't used an UpSquared before and I can't return it because it took me a few weeks to find a power supply and mSATA card.

I am reaching out regarding an issue with my UP Squared Pro 7000. The USB-C port became damaged while switching between device mode and host mode. Unfortunately, it is now non-functional in both modes.

Could you please advise if any hardware support or repair service is available for this issue? I would appreciate any guidance or assistance you can provide.

I have an old upsquared board, which supports realtek c822 chipset as per my lspci command log.

I am trying to install drivers and setup the bluetooth. But I haven't found the way to enable and get it running.

Please help me resolve this and get the bluetooth up.

[ System Info ]
Model: UP Squared i12, Intel Core i7-1260P
OS: Ubuntu 22.04.5 LTS
Kernel: 6.8.0-50-generic
Driver: pinctrl-upboard (v1.1.6)

[Observations]
When executing "dmesg | grep tty*", ttyS4 and ttyS5 appear to be activated.
[2.988076] dw-apb-uart.6: ttyS4 at MMIO 0x4017006000 (irq = 16, base_baud = 6250000) is a 16550A

[Run Test]
1. To perform the UART Loopback Test, pin8 and pin10 were connected with a jumper.
2. Open terminal “screen /dev/ttyS5 115200”.
3. Enter text into the terminal to perform an echo test.

[ Result ]
Characters entered in the terminal are not echoed.

[Question]
I also tested this setup under Ubuntu 20.04 with kernel versions 5.15.x and 5.4.x, but the issue persists.
Could you help identify the issue or suggest further debugging steps?

Thank you!!

A breast lift (mastopexy) is a popular cosmetic surgery that helps to restore a youthful, firm, and lifted appearance to sagging or drooping breasts. Whether due to aging, pregnancy, or weight loss, many women turn to breast lift surgery to enhance their silhouette and boost their self-confidence. While the procedure can be quite costly in many countries, Turkey has become an increasingly popular destination for breast lift surgery, offering affordable prices without compromising on quality. In this article, we’ll explore the factors that influence the cost of a ****
**** and why it’s an attractive option for medical tourism.

What is a Breast Lift Surgery?

A breast lift involves removing excess skin and tightening the tissue to raise and reshape the breasts. The procedure is tailored to each patient’s unique anatomy and aesthetic goals, often combined with other enhancements, such as breast augmentation, to improve volume and shape.

A breast lift can address several common concerns:

• Sagging or drooping breasts
• Loss of breast volume and firmness
• Uneven breast size or asymmetry

Cost of Breast Lift Surgery in Turkey

One of the main reasons patients choose Turkey for their breast lift is the significant cost savings compared to countries like the United States, the UK, or many parts of Western Europe. The price for a breast lift in Turkey typically ranges from $2,000 to $4,000 depending on several factors.

Key Factors That Influence the Cost

1. Surgeon’s Expertise and Experience: The cost can vary depending on the surgeon’s skill and reputation. Highly experienced surgeons with advanced techniques may charge a higher fee, but their expertise often results in better, more natural-looking results.

2. Type of Procedure: The complexity of the procedure and whether it is combined with other surgeries, like breast augmentation, can impact the final cost. Simple breast lifts tend to be more affordable, while combined procedures (e.g., breast lift with implants) may increase the price.

3. Location of the Clinic: Istanbul, Antalya, and other major cities in Turkey are home to many of the country's top cosmetic surgery clinics. Clinics located in larger, more popular cities may have slightly higher fees, though the prices are still significantly lower compared to many Western countries.

4. Hospital or Clinic Facilities: Accredited clinics with modern equipment and high standards of care may charge more than smaller or less equipped centers. However, the cost is generally still much lower than what you'd pay in other parts of the world.

5. Additional Services: Many clinics in Turkey offer comprehensive medical tourism packages, which may include pre-surgery consultations, transportation, accommodation, and post-operative care. These packages can add to the overall cost but also provide additional value for international patients.

Why Choose Turkey for a Breast Lift?

1. High-Quality Care at Affordable Prices: Turkey offers exceptional cosmetic surgery options at a fraction of the cost seen in countries like the U.S. or the UK. This makes it an attractive option for individuals who may not be able to afford breast lift surgery in their home country.

2. Experienced Surgeons and Modern Facilities: Turkish clinics are known for their skilled, internationally trained surgeons who specialize in breast lift procedures. These clinics are equipped with state-of-the-art technology and adhere to rigorous safety standards, ensuring that patients receive high-quality care.

3. Medical Tourism Infrastructure: Turkey has become a hub for medical tourism, offering a well-established infrastructure for international patients. Many clinics provide all-inclusive packages that include surgery, aftercare, accommodation, and even airport transfers, making it easy and convenient for patients traveling from abroad.

4. Positive Patient Experiences: Turkey has built a strong reputation for cosmetic and aesthetic surgeries, with many patients returning home with impressive results. The combination of cost-effective procedures, world-class care, and the country’s natural beauty makes it an ideal destination for those seeking a breast lift.

What is Included in the Cost?

The cost of a breast lift in Turkey typically covers:

• The surgeon’s fee
• Anesthesia and operating room fees
• Pre-operative consultations and medical tests
• Post-operative care and follow-up visits
• Hospital or clinic stay (if required)

Many clinics also offer additional services like transportation and accommodation for international patients, which can be included in the overall package price.

Conclusion

The cost of a breast lift in Turkey is significantly lower than in many Western countries, yet it doesn’t compromise on quality or expertise. With highly skilled surgeons, modern medical facilities, and the availability of all-inclusive packages, Turkey is an excellent option for those considering breast lift surgery. Whether you are looking to enhance your body contour or restore youthful breast shape and firmness, you can enjoy affordable, world-class care in Turkey. By choosing Turkey for your breast lift, you can achieve the results you’ve always wanted at a fraction of the cost, all while benefiting from a relaxing medical tourism experience.

I have a system that sometimes take a lot to boot up. It appears black screen and after a few minutes the system goes on. Other times boots instantly.

I'd like to know if changing the Watchdog setting in the BIOS from 300 to 15 seconds it may help to reduce the time that holds at startup. I've checked and it seems that the time with black screen reduces significantly, but I'm not 100% sure if this setting applies here.

Could it help?

Thanks in advance.

Best regards.

I built a Yocto image (dunfell 3.1.7) for the Upboard and copied the generated .hdd image to a bootable USB drive. However, after connecting the USB drive to the Upboard for flashing the eMMC, the system does not boot and keeps looping in the boot menu.

I followed the instructions provided in this link for building the Yocto image : https://github.com/AaeonCM/meta-up-board/tree/dunfell?tab=readme-ov-file

I have also attached the image for reference.

Can you give instructions on how to use it in the B-Key?

In Ubilinux 4 running on our UP Boards, we can see the TCO watchdog:

We cannot get the iTCO watchdog to show up under /dev/watchdog in Ubuntu. Have followed the instructions on your Github and set up Ubuntu desktop 20.04 correctly as per these instructions yet the iTCO watchdog doesn't display.

What kernel should we have installed to get the watchdog working? We installed:
Linux upxtreme-UP-WHL01 5.4.0-1-generic #2~upboard2-Ubuntu SMP Thu Jul 25 13:35:27 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux as per the instructions.

Should we be using a different kernel to get the iTCO watchdog on an UP Board? We don't want to use Ubilinux anymore so need this to work in Ubuntu.

P.S. we need the iTCO watchdog, not a softdog.

How can this new device type recognition be backported to the old v5.4 kernel supported by UP-Board https://github.com/up-board/up-community/wiki/Ubuntu_20.04 ?

I'm looking to use the UP Squared Pro 7000 as USB device. According to the USB controller used for the CPU, It is possible to configured it as USB device but I can't find any settings to enable it on BIOS side. Is it possible to enable it ?

Regards Romain.

is Ubuntu still supported?

If yes, what is the further plan?
Unfortunately, the current plan ends in 2021

On the 7000 Pro, the x7425E's UART0 appears to be the one connected to pins 8 and 10 on the 40-pin header. I'm not really looking to use this as a general-purpose COM port like many of the answers I've been finding here and on the Wiki. Rather, I'm using the 7000 Pro to prototype firmware that will eventually run on a custom board that will have one of the SoC UARTs permanently wired to an on-board custom ASIC. That resource will be shared among multiple applications, and the framework of a UMDF2 or KMDF driver is perfectly suited to managing that.

While I have some Windows driver experience, I'm new to both ACPI and SerCx2.

After going into the BIOS CRB Setup > CRB Chipset > PCH-IO Configuration, enabling UART0 in ISH Configuration, and setting the UART0 Controller to "Communication Port (COM)" in SerialIo Configuration, and uninstalling the Intel UART controller driver (iaLPSS2_UART2_ADL_N.sys), I have both Mincomm and PuTTY able to echo characters through COM3 (alias "\?\ACPI#PNP0501#SERIALIOUART0#{86e0d1e0-8089-11d0-9ce4-08003e301f73}"). It looks like the system is well equipped for my development needs.

So, with Microsoft's SerCx2, I think the basic idea will be to change the UART0 Controller to simply "Enabled" and install Intel's UART controller driver, which I believe fulfills the controller part of the SerCx2 architecture, plugging into the SerCx2 framework that provides the API my peripheral driver will use.

As I understand it, I need to add a Device object in ACPI to represent the custom ASIC, and the hardware ID I declare there (_HID) is what I'll place in my driver's INF file to get it loaded when Windows starts.

The part eluding me at the moment is how to write my Device object's ASL to link the appropriate object representing UART0. The custom ASIC should look to Windows like a fixed non-PnP device attached through a UartSerialBus, I think.

Which object do I need to link to (\\_SB.PC00.UA00, maybe?) and what and how do I express this connection in ASL?

Is there any documentation that relates the gpiochip and line to the 40pin interface?
Comments in the forum suggest the following:
https://github.com/up-board/up-community/wiki/Pinout
But I can't find the gpiochip(n) and line(m) mapping. Where can I find this?

Through some testing, I was able to toggle the blue LED, and some GPIO's that I configured in the BIOS as outputs. Here is what I've found:

For example, the following toggles the Blue LED:
gpioset gpiochip0 73=1
gpioset gpiochip0 73=0

The following toggles pin 13 (also referred to as UP pinout GPIO4, or Linux GPIO 27).
gpioset gpiochip1 75=1
gpioset gpiochip1 75=0

FYI - using a previous kernel with sysfs(Centos 7.x), I was able to toggle pin 13 using the following
echo "1" >> /sys/class/gpio/gpio432/value
echo "0" >> /sys/class/gpio/gpio432/value
But this is now deprecated.

Here are a few pin associations I've been able to verify:
gpioset gpiochip1 38=$value #this controls pin 18
gpioset gpiochip1 74=$value #this controls pin 15
gpioset gpiochip1 73=$value #this controls pin 29
gpioset gpiochip1 37=$value #this controls pin 31

I can control a pin using gpioset, but when I read the same pin back, it sets the output to 0.
For example
gpioset gpiochip1 75=1 #output is asserted hi
gpioget gpiochip0 75 #this value reads back as zero, and the output is set to 0 (low).

Lastly, when I read chip0, pin 72, all three (red, green, yellow) LED's turn off.
gpioget gpiochip0 72 #turns off three LEDs

And when I try to set gpiochip0 72=1, the LED's do not restore.

Any clarification would be helpful.

Seems there should be a grommet for mounting a M2 card, and a slightly shorter post to line up with the other three.

My work around was to leave out the post above the M2 mount.

Am I missing something?
