How can i enable the udc device on 5.18.19 kernel


舒恺

Question

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.

What patches should I add?

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

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 :)
