configfs not mounting under /sys/kernel/config during boot

[SirMaximilian]

configfs is not mounting at boot causing the script /opt/nvidia/l4t-usb-device-mode/nv-l4t-usb-device-mode-start.sh to fail with mkdir: cannot create directory ‘/sys/kernel/config/usb_gadget’: No such file or directory. Without the device mode the USB serial, network, and mass storage aren't starting. I'm able to mount configfs once the system boots with mount -t configfs none /sys/kernel/config

I'm also experiencing issues with the rootfs not expanding and dns not resolving as well.

Ive gotten Ubuntu 22.04 to build by not installing python-is-python2 and removing the python2 jetson-gpio lib with RUN rm /build/Linux_for_Tegra/tools/python-jetson-gpio_*_arm64.deb after extracting the BSP

I'm aware of those issues. Fixes are coming this week or next week. Meanwhile check the open issues, you'll find the fixes there

[SirMaximilian]

any updates? could you share what you think is causing the mounting issue?

[pythops]

For the DNS, you can fix it this way

# echo "nameserver 8.8.8.8"  > /etc/resolv.conf
# chattr +i /etc/resolv.conf

For the rootfs not expanding, can you share what makes you think it's not expanding ? the output of lsblk -f and df -h commands for instance

About the mounting issues, I never had that before. What board are you using ?

Thanks for the tip.

I confirm the issue with the resize. if you reboot then it will work.

$ sudo systemctl status resizerootfs.service

I'll fix it in #103

[pythops]

Fixed here #103

For the mount issues, I can't reproduce the issue. the configfs is mount correctly

Sorry for the late reply but this issue still persists when building with ubuntu 22.04. I've gotten it to build with 20.04 and the configfs mounts correctly.
