I recently purchased an A02 and B01 development board, and they both booted normally for the first time, but after I flashed dtb with the following command, they were stuck in recovery mode and could not boot:
sudo reboot --force forced-recovery sudo ./flash.sh -k DTB jetson-nano-qspi-sd mmcblk0p1
Making a new sd card image does not work either.
Even if I don’t insert the sd card, I can still see the ID 0955: 7f21 NVidia Corp through lsusb.
What should I do to make it work?
