Strange behaviour on NiosII/f

Hi All, We are using Nios for a while now and recently ported our code to NiosII. Everything was running stable on a NiosII/s core. Then I tried to run the same code on a NiosII/f and it failed...

Hi again,

Can anybody (maybe from Aletra?) explain this? It seems that instructions directly after the WRCTL instruction get wrong values from the registers (in some cases). I can't imagine that this is a feature, so it must be a bug in the /f core. Or is a 'flushp' required after the WRCTL? I did not find anything about it in the manuals.

Kind regards,

Tim Brugman.
