I guess you mean SBC35-A9G20?
Everything seems to work properly except the RTC. They use the same M41T94
part and the CS is the same

Currently, I don't really have any idea. Besides, it's going to be hard for me
to debug this, as I don't have an oscilloscope at hand. Would you please try
to
run u-boot within a debugger to see where exactly the CS line is driven low?

I actually tried it with the patches for both boards (TNY SBC35) and
saw the same result.

That is certainly possible. This problem went away for me when I upgraded to
the next branch.

Hello Albin,
I tried using your patches for the TNY-A9G20 on my QIL-A9G20 board from
Calao. Everything seems to work properly except the RTC. They use the same
M41T94 part and the CS is the same on both boards (PA3). I can set the RTC
using the date command and read back the value okay.
