I want the interface to be simple when I boot up. I need to modify the UEFI boot logo and close the printing of text information.

I followed the documentation:

How can I remove text printing from the UEFI Logo interface? - Jetson & Embedded Systems / Jetson AGX Xavier - NVIDIA Developer Forums

Step 1: removing the ErrorPrint calls.in L4TLauncher.c(Path:home/zynq/nvidia/nvidia-uefi/edk2-nvidia/Silicon/NVIDIA/Application/L4TLauncher/L4TLauncher.c
)
Step 2:edk2-nvidia/Platform/NVIDIA/Jetson/build.sh.
Step 3: cp /home/user/nvidia-uefi/images/uefi_Jetson_RELEASE.bin Linux_for_Tegra/bootloader/uefi_jetson.bin
Step 4: (Path:~/nvidia/35.3/Linux_for_Tegra/source/public/kernel/kernel-5.10/drivers/firmware/efi/libstub).
efi-stub.c
fdt.c
efi-stub-helper.c
I tried deleting the three files, but refactoring the kernel was not successful.

Hello,

Thanks for visiting the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

I will move this post over for visibility.

Cheers,
Tom
