5 years ago @myfreeweb Try latest commit, and make sure you have microSD inserted in. Do you have UART access? If so, we can diagnose issues more easily.

5 years ago So the first non-working revision is 9e2a0f7 SDMMC: Take offline for bugfix. I just noticed that you changed the memory address of the framebuffer in that revision…
UART access
Well, I have a very janky cable that used to mostly work and I don't remember which pin is what anymore… anyway, it would only show coreboot output, right?

For UART, I haven’t port the actual serial I/O library, but it should be an easy task. Currently you don’t see log in UEFI, it is normal.

Hi, thanks for this project!
I've been able to run version d2b9bd6a68b926e43eab50b639726e67120c6d82 (and after fixing
if (sdmmc_storage_init_sd…)→if (!sdmmc_storage_init_sd…)it even boots from SD, though I was getting weird page faults when booting FreeBSD — probably because of #3 MMU stuff that wasn't fixed then?)Newer versions with the stuff ported from u-boot don't display anything on the screen, it lights up and stays blank :(
