Q: There is a wait in UEFI stage. How to disable it to accelerate system booting?

Please refer to the UEFI source
edk2-nvidia/NVIDIA.common.dsc.inc at main · NVIDIA/edk2-nvidia · GitHub

gEfiMdePkgTokenSpaceGuid.PcdPlatformBootTimeOut|L"Timeout"|gEfiGlobalVariableGuid|0x0|5

This 5 seconds is for user to interrupt and enter UEFI menu. It could be customized setting to 0 to disable.

Q: Is there any tips for debugging UEFI?

Please rebuild the UEFI source with the link above. After you rebuild it, there would be a debug version of binary. Please replace the old “uefi_jetson.bin” file in your BSP folder and then reflash the board. It will enable full log in UEFI.
