Hello,
After a few years, I tried updating my u-boot 2021 to a more recent version, as the linux kernel complained "ATF needs update". The device I'm using is a nanopi neo3 2GB (more or less the same compared to NanoPi R2S, both RK3328 platform).
Starting from 2023.04-rc1, I couldn't get it running: in TPL, it complained "out of memory". A hint on IRC made me pull back to v2022.04, which works with a few mods, but there's one (minor) thing not working: board_misc_init() causes a function call failed. Probably because efuse isn't working properly? I also had to modify the device tree a bit:
I have the Rock64 running 2022.10 without issues.

But starting from 2022.07, the system simply prints (in TPL) "data training error" and gives up (using default values in "make oldconfig". I have the config files of both 2022.04 and 2022.07 attached, any clue why it's no longer working?
Kind regards,
