I know how to update MB1 BCT using flash script on host side:
sudo ./flash.sh -k MB1_BCT jetson-xavier mmcblk0p1
But I want to update MB1 BCT on Xavier side. How can I do it?
It seems that MB1_BCT is in sdmmc_boot partition instead of sdmmc_user partitions.
Which emmc partition/device name should I use to upgrade MB1_BCT?
