Hi guys.

I've been working with the 4.19 kernel before on M2.
I upgraded to the kernel version 5.18 today.
I found that I can't find the registered udc device anymore.

This is auto-registered on the 4.19 kernel and you can find it under /sys/class/udc.

root@station-m2:/boot# ls /sys/class/udc
fcc00000.dwc3

 

I would like to ask how to enable the udc device on the 5.18 kernel.

Thank you.

Add the necessary patches and build a new kernel.

Sorry, because of the posting time limit, I can reply to the message just now。

What patches should I add?

I don't know much about the files or configurations required for this feature.

Thanks.

You have to create these patches yourself (study the design, drivers, DTS and create the necessary fixes).

This is a measure that is unfortunately needed to fight spam in our forums. You don't see any because we're doing a pretty decent job  keeping it clean

Anyway this restriction will lift automatically after a short while for genuine users
