The “To flash the bootloader and kernel” sector in official l4t 32.1 document use the “sudo ./flash.sh ” command to flash bootloader and kernel, but that means flash the whole rootfs including bootloader and kernel.
Flash the kernel can use “sudo ./flash.sh -k kernel --image <user_path>/Image jetson-tx2 mmcblk0p1”, and the bootloader, I think, can use a command like “sudo ./flash.sh -k cpu-bootloader -L <user_path>/Image jetson-tx2 mmcblk0p1”. But how flash flash rootfs(not including kernel and bootloader) into specific partition.
