VIM3

I am trying to use USB OTG on VIM3 with Ubuntu 20.04 Kernel 5.18 Mainline image.

I enable the option in /boot/env.txt
overlays=… otg-device

And followed this forum

But still not work

5.x kernel doesn’t support such overlays.

Can you try this ?

$ cd /tmp
$ wget https://dl.khadas.com/.test/libcutils.so
$ sudo cp libcutils.so /usr/lib
$ sync
$ sudo reboot

And try again.
