Optimize UEFI boot black screen time

Hello, UEFI timeout duration 5S is set to 0S,there are a lot of black screens in UEFI startup, taking 4 to 5 seconds each time, can this be optimized,The two black screens occupy about 10S in total

Hi liuzc620,

Are you using the devkit or custom board for Xavier NX?
What’s your Jetpack versin in use?

Have you flashed the custom build UEFI binary?

That is not just black screen. If you flash the debug UEFI binary, you would see what it is doing at this moment.

UEFI(bootloader) will initialize many functions and they could be optimized according to your use case.
You could remove some features in the following 2 configuration files with your needs.
