Honored ContributorProblems with read transfer
I have connect a simple read-write- component in my system. When i do a read transfer, i only get the hexidecimal value ffffffff and i don't know why. ... unsigned long read; read = IORD_3...

Honored ContributorI think that when you have low active signal (as you did for the read and write enable signals), you need to end their name with _n instead of just n. If SOPC builder doesn't see the _n in the name, it will assume that they are active high signals.
Either rename then with something that ends with _n or use them as active high signals in your code.
