USB storage not found in U-Boot - Apalis iMX8 and Ixora 1.3A

Hi,

I’m currently experience the same issue like in USB storage not found in U-Boot when using USB Hub - Apalis iMX8 with the Ixora 1.3A Carrier Board and an Apalis iMX8 QuadPlus 2GB.
If I put the apalis into an ixora 1.2A the usb storage device is detected in u-boot.
The workaround with setting GPI 132 works for me too.
I’m on the Toradex Reference Image TDX Wayland with XWayland 6.3.0-devel-20230626+build.320 (kirkstone) apalis-imx8-07314409 ttyLP1

So we maybe need an change in the device tree in u-boot?

Hi @jonas-licht,

Thanks for reporting.

Do you see the same behaviour if you use the Toradex Reference Image 6.2 instead of 6.3 ?

Best Regards
Kevin

Hi,

sorry for the delay, I was on vacation.

I see the same behavior with the 6.2 reference image:
