Hi Bob,
thanks for the reply!
Now that there's a working u-boot for the board - I've got two to choose from now :) - I'm going to be concentrating on trying to get the Mali graphics working as it's a requirement for my project. I've got a working kernel (6.1.31 with patches) but I can also see that work's been underway to bring the support to 6.7. I tested 6.7-rc2 today and can't get any output at all on the console after u-boot starts the kernel.
Yeah, that's because we don't have any video (HDMI) output support (something completely unrelated to Mali, which is just a 3D renderer!) yet in mainline. Jernej was sitting on *some* patches for a while, but didn't have the time to upstream them, and IIUC there is something odd to fix first before it's mainline ready. There are some rough bits in here, and in other repos floating around: https://github.com/jernejsk/linux-1/commits/h616-hdmi-v2
The lack of console output I referred to was over the serial port. I expected that when I swapped out my modified 6.1.31 kernel for 6.7-rc2 that I would still get serial output but nothing; the dtb in mainline looks pretty sparse compared to mine.
Cheers, Andre
