Hello All,

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.

Ubuntu 22.04 mraa

Hello,

I'm having issues trying to get GPIO functionality on Ubuntu 22.04 working. I installed the pinctrl package and built & installed mraa from source, but running mraa-gpio list gives me "no pins". The mraa examples also seem to error out not being able to find pins. Any solutions?

I learned that MRAA can't be used on UP Squared V2.When can we use it?

I2C fails when multiple sensors are connected

anishrr — Tue, 16 Jan 2024 15:19:31 +0000

Hello all,
I am using up2v2 with ubuntu (kernel: 5.15.0-91-generic). I am facing a problem with I2C port when multiple slaves are connected to it. I used a logic analyzer to probe SCL and SDA pins. The active low voltage of SDA and SCL pins are not zero (It was around 300 mV).
To be sure, Then I configured the SDA and SCL pins as GPIOs and measured the active low voltage. It was the same 300 mV.

Is there a way to make the active low voltage close to 0 V.?

UP Squared V2 I2C Problems

Fri, 14 Jul 2023 12:29:32 +0000

Hello,

We are using the upboard for several years in our projects and are looking to switch to an UPBoard Squared V2 solution. Now i'm struggling to get the I2C ports to work in a reliable way. I hope i can explain my problem in a clear way.

System:
On the system we have installed Intel IOTG Ubutu 20.04.6 OS with the UP HAT pinctrl-upboard driver discussed in this post:
https://forum.up-community.org/discussion/5138/ubuntu-22-04-mraa#latest

The system has a bios version UPS-EHL01 R1.0 from august 2022.

We are using both I2C ports on GPIO 2,3 and 27,28.
We have 2 chips with ID 20,21 connected on 1 I2C port and a seperated chip with ID8 on the 2nd I2C port. When using I2Cdetect sometimes i can see and use the chips with no problem at all.

The problem is that sometimes after a powercycle one bus isn't working anymore and the other bus suddenly is available on a different bus nr.

The missing chip on bus 5 is most of the time nowhere to be found, after a few powercycles sometimes its visible and working fine. I'm sure its not an hardware problem, when connection an UPBoard all is working fine.

We also use the SPI bus, we dont experience any problems using this.

Also the are a few errors when Ubuntu is starting up, perhaps this information could be of use for someone?

Is anyone able to point me in the right direction how to solve this problem?

Thank you in advance.

I2C Set Speed

I have an application were i need to use 100khz mode on the I2C

I've used CRB Settings to change all the I2c Buses i could find on the Bios to Standard Mode, it always runs on 400Khz mode.

I've got a I2c device on I2C1 (on Pin 3, 5).

Upboard Squared V2
Bios: USEHAM13

I've looked to the signals with a logic analyser

Thanks for your help

OpenVINO hang on UP2 V2 GPU

Kahren — Fri, 10 Mar 2023 03:21:05 +0000

I recently purchased UP2 V2 with certified Ubuntu preinstalled. Code that ran on UP2 V1 with openVINO 2021.4.2 LTS on GPU stopped working. Loading the AI kernel/network fails. I found this https://github.com/openvinotoolkit/openvino/issues/9884 which shows there is a problem with EHL GPU but it is not clear as to the fix. Is this a known issue with Up2 V2? is there a fix?

Hello,

I see that Up Squared V2 is listed as only supported with Ubuntu 20.04 and Yocto 3.1.

Is there any plans for making support for Ubuntu 22.04 or Yocto 4.0?
