[U-Boot] Issues when saving environment in RK399 RockPI 4

[U-Boot] Issues when saving environment in RK399 RockPI 4

[Ezequiel Garcia]

I decided to test latest U-Boot, following instructions in
doc/README.rockchip. The instructions seemed
clear and I could build this easily.

However, there seems to be an issue when I save the environment. Any ideas?

=> reset

I have observed issues like this with i.MX when U-Boot size grew and
overlapped the environment variable region.

Here is one commit that fixed the issue for mx53loco board:
https://gitlab.denx.de/u-boot/u-boot/commit/033f6ea5fa5fce63d52c8c2b63d8284144415b88

Try to investigate if this could be cause of the issue you are seeing.

You could also try the first two patches from this series:
https://patchwork.ozlabs.org/user/todo/uboot/?series=132338

Maybe you are hit by the over-writing discontiguous files bug in the FAT code.

It's probably something along those lines. OTOH, it seems RK3399 is under going
some more work, judging by some patches recently sent. I decided to go back
to some vendor bootloader until upstream settles a bit on the stable side.

Will be getting back to this sooner or later.

Thanks again,
