How do I update cboot separately by nvmflash.sh?

Hello, at present, our factory line is using the package mfi_jetson-xavier-nx-devkit-emmc.tbz2 made a few months ago, which is used for production system burning. Now that I’ve done a minify of cboot, use the following command to generate cboot_t194_sigheader.bin.encrypt, Can this directly replace cboot_t194_sigheader.bin.encrypt in mfi_jetson-xavier-nx-devkit-emmc? I did some tests and it started up fine, but I was worried about some other issues. Is my method canonical and admissible? Please let me know. Thank you

sudo ./flash.sh --no-flash -r -k cpu-bootloader jetson-agx-xavier-devkit mmcblk0p1

Also, in mfi_jetson-xavier-nx-devkit-emmc, can you write cboot alone? thank you

Hi,

I think you are doing it right.

Do you mean updating specific partitions with massflash?
I think it’s not supported, and you may only do a whole re-flash.

Ok, I understand. Thank you very much for your answer!
