Verify problem while runing on Nios II hardware

Thanks to all for your suggestions! I checked the pin assignment and it's perfect,there aren't problems. Also, the sys_lib is OK, I choose the SRAM memory as place for my code. The clock signal has the appropriate pin.

I fixed the problem, it was my mistake because I set the data bus as only output direction and now I use it as bidirectional direction and it works. Sometimes we have to look for the simpliest causes :rolleyes:. Before i fixed the problem I tried many options. Jakobjones gave me very good suggestions.

Again, thanks to all, Lightline you was right and if I wouldn't fix it before your

suggestion were good!

Best regards!
