Tonight, I finally managed to build an image on the OPI4a itself. However, after writing it to the eMMC using Balena Etcher, the board did not boot. If I understood Nick A's message correctly: 'Orangepi 4a uses the same radxa-a5e_defconfig. https://github.com/warpme/minimyth2/blob/master/script/bootloaders/board-t527.orangepi_4a/Makefile', I needed to select the radxa-a5e board from the list.
Here's what I did:
bash
git clone https://github.com/NickAlilovic/build.git --branch warpme-6.12 --single-branch cd build ./compile.sh
I selected the radxa-a5e board, edge, bookworm, server, standard. The image was compiled, and then I wrote it to the eMMC via Balena Etcher.
After powering on, the board shows no signs of activity. I suspect that some patch or bootloader was not included in the image. Unfortunately, my knowledge is insufficient to understand what I did wrong and how to fix the issue. I kindly ask for your help.
