Hi @rock. Thank you. I tried to put a clocking wizard outputting 200MHz from FCLK0 (100 MHz) and it did not work.
Actually my PS clocks right after boot are 150, 214.28, 300 and 150MHz. It is really odd that these values are approximately [100, 142.86, 200, 100]x1.5.
I don’t really understand what is going on.
Only when I force clocks to [100, 142.86, 200, 100] is that I could get [100.0, 150.0, 214.285714, 166.666667].
I checked that Zybo crystall oscillator is 33.3333MHz, whereas PYNQ-Z2 is 50MHz (1.5 times higher).
I am a bit frustrated for now, once I can’t understand what is going on.
Thank you for the support anyway.
