Understanding the ConfigFs for iMX8m and Android 11

Hello,

I have an i.MX8M processor for a custom Android board. I am attempting to port Android 11 onto it. During this porting process, I am encountering issues with ADB over USB and suspect that there is some problem with the ConfigFS mode.

I notice statements like configfs=<0/1/2> in the rc scripts and would like to understand the significance of these numbers.

Currently device is detected as RNDIS device, and because configfs not functional its not able to set it to Google device. Following are the relevant debug log statements -

[ 24.401380][ T33] usb 1-1: New USB device found, idVendor=0525, idProduct=a4a2, bcdDevice= 5.10
[ 24.401380][ T33] usb 1-1: New USB device found, idVendor=0525, idProduct=a4a2, bcdDevice= 5.10

For more details, please find the attached text file.

I appreciate your help in advance!

Hello,

Which android is this? because appears to be wrong one of the partition, so i guess rebuild and burn again. You should try the android 13 that is poster on the web site.

Appreciate your prompt response!

Since Android 11 is a crucial requirement for our project, migrating to Android 13 is not an option. Could you please assist us in addressing the issue specifically for Android 11?
