Hi, Pillemann

I assume in 03700000 flash is maped

Plz read the data sheet of your flash and find out the maximum write time for the flash.Once you got the write time ,open the SOPC builder and double click on the CFI Flash give the wait state as the write time.(If you don't know the wait state then give an arbitrary value setup and hold time =1 cycle and wait state=50 cycle(the unit should be in cycles)).
