Currently, I only want to test with three Jetson devices. I managed to run one, but it encountered the following error:
��I/TC: Reserved shared memory is disabled
I/TC: Dynamic shared memory is enabled
I/TC: Normal World virtualization support is disabled
I/TC: Asynchronous notifications are disabled
E/TC:? 0 jetson_user_key_pta_uefi_vars_auth:920 UEFI variable auth key not set !

ASSERT [FvbNorFlashStandaloneMm] /dvs/git/dirty/git-master_linux/out/nvidia/optee.t194-uefi/StandaloneMmOpt)
I tried Method link, but it didn’t work. Here is my process:
echo "5xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" > kek2.key
echo "00000000000000000000000000000000" > sym2_t194.key

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --showlogs --flash-only
cd bootloader
sudo bash ./flashcmd.txt
However, when I ran the last command:
sudo bash ./flashcmd.txt
I received the following error:

I need help troubleshooting this device error, and then I would like to proceed with testing on two more devices. Afterward, please guide me on how to perform mass production (with over 20 Jetson devices).
