I follow the link below to build a custom UEFI image. and replace the BOOTAA64.efi and uefi_jetson.bin files in bootloader directory so how can I flash the new UEFI image into orin agx? flash.sh? and what’s the detailed instructions？
You can try to do full flash and it shall be updated.
yes，it may help，but i mean if there are a single cmd to flash only uefi, so it can save time。。。
“-r” can skip the generation of system.img.
“-k partition_name” can flash the partition only.
And you can check the partition name in those xml files under your Linux_for_Tegra/bootloader.
These didn’t change between rel-32 and rel-34.
I follow your suggestion and it success to flash the new uefi but there‘s some thing wrong with uefi pictures.
so let list the progress.
I wanna to replace the uefi picture, so I follow the instructions as below:
then I rebuid the uefi source code according to the instruction: Home · NVIDIA/edk2-nvidia Wiki · GitHub
next I got BOOTAA64.efi and uefi_jetson.bin files and replace the file in bootloader directory.
finally I flash the whole image as you mention above.
after reboot I didn’t get the expected picture and it’s just black!
so if there is some thing wrong with my method, and any suggestion? thank you!
Let me try it on my side.
Also, is it okay to change this topic to “cannot change boot logo”? This will be more specific to your topic.
hi @WayneWWW ,is there any update about this topic? waiting for your reply~
Hi, I have the same problem, I cannot change the logo Flashing error after uefi boot logo changed for Jetson AGX Orin
Hi @mmcly when you use sudo ./flash.sh -r -k <partition_name> jetson-agx-orin-devkit mmcblk0p1 what name did you use?
I see from Linux_for_Tegra/bootloader/t186ref/cfg/flash_t234_qspi_sdmmc.xml several list of Jetson AGX ORIN partitions. Should it be A_cpu-bootloader or B_cpu-bootloader associated to TBCDTB-FILE the partition we have to update?
I notice from Partition Configuration — Jetson Linux<br/>Developer Guide 34.1 documentation that TBCFILE associated to uefi_jetson.bin is missing on flash_t234_qspi_sdmmc.xml
infact, i didn’t use a single part to flash, I just follow @WayneWWW suggestion to use a full flash…
but what you said, I think is right, so maybe this a bug in jetpack5.0DP, right?
