USB gadget configuration through configfs on VIM3l

Technical Support
1

Hello,
I’ve been trying to use my khadas vim3l as a USB device who can both be used as a router and a mass storage device.
This is something I have already done on a rpi4 at my place using configfs with a bash script looking like this:
https://pastebin.com/raw/b1qTDrPd

Using the same script on vim3l on a 4.9 ubuntu i can only get the RNDIS gadget working and not the mass storage and neither of the two on a 5+ ubuntu image.

I think I am missing something somewhere but since it’s something very new for me I can’t find any solution.

I am hoping someone could help me find a solution.
Thank you.

Expect you will need to make sure the appropriate options are set in the kernel and rebuild if they aren’t there.
