Hi again,
We managed to fix our loading problem.
The bug was due to our FPGA binary, not the loader itself.

Hi Mike,
Thank you very much for the fast response.
We are loading the FPGA from Linux, but not with the "fpga_... Kim Nielsen

Hi Mike,
Ah, makes sense.
For the time being I'll stick with controlling the clock frequency with Linux.
Thank... Kim Nielsen

Alright.
Is there is no way to change the default frequency from 300Mhz to e.g. 372MHz with U-Boot?
As far as I ... Kim Nielsen

I actually got another question.
By default, the cpu frequency seems to always be 300 MHz.
Is this value hardco... Kim Nielsen
