AGX Xavier-NX BCT Burning CMD

How does AGX-Xavier NX burn BCT separately and what are the burning commands?
now we used the cmd below:
sudo ./flash.sh -k MB1_BCT jetson-xavier-nx-devkit-emmc mmcblk0p1

but when it was burning into board, the systerm is can’t start!

Hi guwen,

Currently there is no method to flash BCT separately.

But you could use the build_l4t_bup.sh to create a new bootloader payload and use it to update. This will also update the BCT.
