The system on SSD is messed up. So I flashed the eMMC again, hoping to format the SSD and setup from scratch again. Flashing is successful. But when I reset the board, it automatically started the system on SSD, not from the eMMC.
Does anyone know how to boot from the eMMC and let me initialize the SSD again?
If this is jetpack4, then modify the boot order in the cbo.dts. Otherwise NVMe has higher boot priority.
Thank you so much for your help.
But when I flash partition CPUBL-CFG, it failed.
The command to flash is:
sudo ./flash.sh -k CPUBL-CFG --image bootloader/cbo.dtb ${BOARD} mmcblk0p1

Which jetpack release is it?
This one
Jetson_Linux_R34.1.1_aarch64.tbz2
Then you are not using jetpack4… The cbo won’t work. Please just operate the UEFI console to change boot order…
OK, I will try
I’m sorry. Where can I find information about UEFI about boot ordering?
My first question is do you know how to get in UEFI console now…
