How can I only update UEFI image

[MicroSW]

I faced this issue,

▒▒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

ASSERT [FvbNorFlashStandaloneMm] /dvs/git/dirty/git-master_linux/out/nvidia/optee.t234-uefi/StandaloneMmOptee_RELEASE/edk2-nvidia/Silicon/NVIDIA/Drivers/FvbNorFlashDxe/FvbNorFlashStandaloneMm.c(868): ((BOOLEAN)(0==1))

it is the same as this: Jetson Orin Nano Won't Boot, Won't Even Display Anything

I don’t want to update all image on the Orin since I have setup some applications, configuration, from image, seems UEFI is broken, can someone tell me how to only update/flash UEFI???

Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!

Hi @carolyuu would you please check it is possible to only flash UEFI only? or Can I read system.img from Broken board, then I can flash it to annother board?? that will save me for re-build or reconfigure my system??
