AGX Xavier sometimes fails to start properly in JP5.1.1

[HuangZeng]

Hello, Nvidia:
On the carrier board we made ourselves, we upgraded Xavier to JP5.1.1, but now we find that it occasionally fails to boot normally, which does not exist on JP4.6.1, so I would like you to help me analyze it. The following is the serial port log of normal startup and non-normal startup.
jp511_startup_failed.txt (10.9 KB)
jp511_startup_ok.txt (78.2 KB)

thanks.

Hi HuangZeng,

I’ve diff both of your logs.
The most difference is about the temperature.

[0000.209] I> Temperature = 39000

The boot up seems failed in UEFI.
Could you help to use debug UEFI to enable the log and share it for further check?
You could refer to the following instruction to setup and build debug uefi binary. (uefi_Jetson_DEBUG.bin).
Build without docker · NVIDIA/edk2-nvidia Wiki · GitHub

hello, KevinFFF
I can’t seem to find a way to compile debug mode uefi bin file on the wiki.Can you tell me where I can see it?
Thanks.

Please just refer to the steps from link I shared.
You should setup the build environment and clone the source.
There 's Build UEFI at the end.
