Hello Sir,

May I know how did you build your preloader? is it through bsp-editor?

Furthermore, which device is that?

Hi,

I suspect that it is issues of osc1 reference clock.

In our case it is 50Mhz, and csel is 0.

Maybe the actual accuracy of our clock is not sufficient ? I haven't find the precision requirement for osc1 in reference.

I also see that it terrasic DE-10 they use 25Mhz as input with csel=0, maybe 50Mhz is too much near the limitation of csel=0 (10 to 50Mhz) ?

Thanks
