Cannot flash the I.MX6 SoloX-based board on Linux. Error: [Failure to claim interface]

andriibr — Thu, 19 Oct 2023 13:21:21 GMT

Hello,

I have an issue with flashing the iMX6 SoloX COM board from Embedded Artists
using uuu.

Info about the board:

https://www.embeddedartists.com/products/imx6-solox-com

I'm following the flash guide below:

https://developer.embeddedartists.com/docs-app/yocto/deploy-images

The steps I take based on the flashing guide:

1) Power ON, switch the board into OTG mode, and reset.

2) Launch the uuu app with a flash script as an argument.

./uuu full_tar.uuu

Flash script contents:

The output I get:

Then, uuu just hangs. But because the bootloader is already in RAM I do the
following:

3) Open minicom -D /dev/ttyUSB0.

The output of u-boot to the serial console via UART:

For whatever reason, `bootcmd_mfg` didn't execute anything, so I manually ran the
bootcmd.

run bootcmd_mfg

This puts the board into fastboot mode, and the flashing process resumes.

Flashing the same release with MfgTool on Windows works fine. Additionally,
flashing the same release on an older version of Ubuntu 18.04 on my coworker's
laptop also works fine. Does anyone have any idea what I'm doing wrong? Or is
there something wrong with my setup? I'm really confused here.

Re: Cannot flash the I.MX6 SoloX-based board on Linux. Error: [Failure to claim interface]

Manuel_Salas — Thu, 19 Oct 2023 15:26:26 GMT

Hello @andriibr !

I was checking the documentation and zip file where is contained the BSP for the i.MX6SX from Embedded Artist and I could see the UUU script is validated with tool version 1.4.243:

Also, I could see you are using a newer version (1.5.125).

Could you please try to run the below command with UUU 1.4.243 version?

$ sudo ./uuu full_tar.uuu

Please try it and let me know how it was.

Best regards!

Thanks for the quick reply @Manuel_Salas

I just tried the 1.4.243, but results are still the same

Re: Cannot flash the I.MX6 SoloX-based board on Linux. Error: [Failure to claim interface]

andriibr — Mon, 20 Nov 2023 08:48:09 GMT

The issue ended up being related to the kernel image inside the initramfs used during flashing, not to the uuu tool itself. I tried kernels from different releases and managed to flash the board with an older one.

The uuu_imx6sx_com_4.14.78 release worked.
