I install fresh copy of Windows 10 IoT Enterprise 64Bit on fresh UP4000.
I have updated the BIOS to GPIO configuration.

I have installed all windows updates and UP drivers from the driver pack.

I receive error EAPI_STATUS_ERROR when starting Hi-Safe v3.
Version number is: 3.11.2.26

After error is closed, when Hi-Safe window appears, no options are able to be selected

Thank you.

Any suggestions?

I am trying to use PWM on the Up 4000. I have created my Windows IoT Core image following your instructions here, and it successfully boots and GPIO works fine. I'm also running with the Up Framework.
I have downloaded your sample, however this does not seem to run. The code:

controller = await PwmController.GetDefaultAsync();  

Fails to run with error:

"Could not set desired frequency."

I have configured the pin in the BIOS for PWM. What am I missing please?
Thanks.

we were finally able to get the 5G-Module with the UP 4000 carrier board working on Ubuntu 22.04.
Now we noticed that the Ethernet-Port is not working any more.
If we disconnect the carrier board, the Ethernet-Port works again, so it seems to be related.

We found nothing about it in the docs or the descriptions of both the carrier board and the 5G-Module.

Does somebody know if that's a known issue or whether this is intentional?

After plug DC 12V in, the blue LED on, the Ethernet RJ45 light on, but not flash, keyboard was connected, and Numlock light on, I can switch it by press Numlock on keyboard, so does the Capslock. But HDMI output shows no signal, in between, for several second the display was total black, "no signal" disappeared, but come back in seconds, then the monitor shut down itself, and stay shut down permanently.

What am I missing? Do I have to buy a Power/Reset Button Cable to make it boot?

It works well with both Windows 10 22H2 and Ubuntu 22.04, but when the system restarted, AX200 doesn't work and it can't be found on device manager or lspci command. It only works back after the system fully shutdown.

I heard some issues about AC9260 and it needs some BIOS setting. Is there a way to solve this problem like AC9260 case?

It is not very critical problem, but it is very annoying when setting up and running the system.

I checked on the specifications of the board. It has realtek board. So drv=rtg seems okay to me.

Any pointers how to resolve it?

aprés avoir installer mon up 4000 dans mon mobilier digital sous linux serveur , depuis 2 jours il a bloqué , la vidéo reste figé, l'horloge aussi , même après avoir coupé le courant et réalimenté il ne veux rien savoir, l'image reste figé... pensez vous que ma carte a flaché ?

everytime i try to install UBUNTU 20.04.5, Give me This error can you help me?

i have done normal installation here.
some adicional information.
i tried define the disk size like
2gb for swap
200mb for EFI
7gb for /
and the rest for home.(6bg+/-)
And then i cant boot.. i just dont know why .
The version of ubuntu is 20.04.5

i have installed Windows 10 and worked just fine.

ls /sys/bus/pci/devices/0000:00:18.?/dw-apb-uart.*/tty/ | grep tty
/sys/bus/pci/devices/0000:00:18.0/dw-apb-uart.3/tty/:
ttyS4
/sys/bus/pci/devices/0000:00:18.1/dw-apb-uart.4/tty/:
ttyS5

Judging by the wiki, the HAT UART should be ttyS5, so to loopback I short the Tx and Rx and run:

sudo screen /dev/ttyS5 115200

But I get no returned chars. I tried on tty4 to be sure but again, no chars.

Further information on my system. ttyAMC0 and ttyUSB0 are known attached devices, they work OK:

sudo dmesg | grep tty
[ 0.132638] printk: console [tty0] enabled
[ 8.074938] cdc_acm 1-6:1.0: ttyACM0: USB ACM device
[ 8.094024] dw-apb-uart.3: ttyS4 at MMIO 0x91224000 (irq = 4, base_baud = 115200) is a 16550A
[ 8.124707] dw-apb-uart.4: ttyS5 at MMIO 0x91222000 (irq = 5, base_baud = 115200) is a 16550A
[ 8.140810] usb 1-5: FTDI USB Serial Device converter now attached to ttyUSB0

Hoping somebody can offer some advice on what else I can check, am I right in thinking ttyS5 is my port?
