We developed L4T R35.2.1 BSP our carrier board with Xavier-NX. When it booted up, the system get hang on UEFI stage.

The patch described HERE is available in the tegra194-p3668-p3509-overlay.dts already.

The error boot log:

How did you apply device tree patch and what ODMDATA is set?

Hi Wayne,
I did not modify anything, just build and flash image.

$ sudo ./flash jetson-xavier-nx-devkit-emmc mmcblk0p1

5

Build what? What are the exact steps to hit error here?

Are you able to reproduce this issue on devkit?

7

It can not reproduce on devkit. I have no idea our carrier board is short of module or circuit. What is the log means?

8

Could you provide the full log?

Also, is this related to PCIe EP or PCIe EP is just your random guess?

9

There is an old system (jetpack 4.5.1) in the NVME module, the uefi boot from NVME and get such errors.
