I’m trying to update the UEFI boot logo to a custom image. I’ve generated 640x480, 1280x720 and 1020x1080 versions of my .bmp image and replaced the default nvidiagray bmp files in edk2-nvidia/Silicon/NVIDIA/Assets/ with my .bmp files. However, after rebuilding UEFI and updating the board, the UEFI boot background is black with no logo. What am I doing wrong?
I resolved this issue based on comments from this thread https://forums.developer.nvidia.com/t/cannot-change-uefi-boot-logo/213739/23
I opened my existing .bmp images in MS paint, and resaved them. This resulted in a slight adjustment to the file size, as noted in the cannot-change-uefi-boot-logo forum post. Now my image shows up during boot as expected.
