Hello,
Yes, it's a known problem. You could even easily find the information
about it in google. This was posted to the U-Boot mailing list some
years ago:
https://lists.denx.de/pipermail/u-boot/2015-October/230749.html
Jaehoon Chung promised to have a look at it, but we haven't
heard anything back since then. Right now you can try to apply
this patch and check if it helps (essentially a revert of
a276172cf32386c211c75638f6bf3c0d59ba03ba):
https://github.com/ssvb/u-boot/commit/3dd6fdb016c088953f5f293d62d6df03a0f48d54
BTW, I can't seem to find any Tiny4412 board support code in the
current U-Boot git master branch. Are you using a patched U-Boot?
And if yes, then do you have plans to contribute these patches?
Thanks.
