MAX10 UFM writing takes much longer than expected

the one which upset my state machine was the fact that waitreq also goes active during a read cycle (fig 10 in the manual says it doesn't!).

Oh, that would explain something... the state machine is constantly reading data from the flash unless it is explicitly trying to write something. When waitreq goes high for reads as well, I'll have to check if this is causing my state machine to wait endlessly (and then run into a very high timeout I have implemented).

Thanks for helping me out with your experience - I'll check and come back to tell about the result.
