Jetson Agx Orin UEFI startup error

[skynet]

When we use Jetson Agx Orin, we occasionally encounter a UEFI error during system startup, as shown in the following figure.

at this time, no matter how many times we reboot the orin, the same error will be reported in uefi startup.

The only solution is to re-flash the UEFI partition。use this command:sudo ./flash.sh -r -k A_cpu-bootloader jetson-agx-orin-devkit mmcblk0p1
But I promise that no one will modify this partition during use, why does it get corrupted?

With devkit or custom carrier board?
Which JetPack SW?

[skynet]

custom carrier board
jetpack SW is 35.1

How frequently does it happen?
Have you tried a later release of L4T?
There’s little we can help if it does not happen on a DevKit.

[skynet]

happen three times in a few months so far
every time after we reflash uefi,it work fine。

Put the full booting log with UEFI debug binary here.
The screenshot does not give much useful information.

Hi,

I am not sure if this is the cause of this issue.

SNP:PHY: PhyDxeInitialization () Failed to configure Phy
DeviceDiscoveryBindingStart, driver returned Device Error to start notification

Do you have RGMII enabled on your board? I guess it should be a custom board here?

1、but normal startup these error also exist, not affect orin uefi startup

2、if these error cause uefi startup failed,why we reflash uefi part ,it work fine.
