triple speed ethernet upgrading to nios ii/f problem

Question

Hi,

I am working on a project on a DE2-115 board that involves both a NIOS processor and the triple speed Ethernet IP core , the problem is that nios ii/e processor works well with the mentioned IP core but when trying to upgrade the processor to nios ii/f it doesn't work and it hangs at the step doing the software reset to the PHY chip.

Do anyone have the same issue, or have any suggestion for fixing this issue ?

Thanks in advance and highly appreciate your response.

Are the Nios II/f and Ethernet IP core running at the same frequency? If they are not in the same frequency, try adding a clock crossing bridge in between them.

Thanks mikedsouze for your reply.

Yes, they are working at the same clock domain (100 MHZ).

Even when I applied the provided example by Altera " Using Triple-Speed Ethernet on DE2-115 Boards " it only works with the NIOS ii/e and doesn't work with NIOS ii/f.

appreciate your help.

Can the system runs "Hello world" ?

altera_forum · Answer

Yes I can run the hello world in case if I bypass this step "phy software reset ", cause the program runs infinitely through the while loop of the mentioned step

Hi,Actually i've the same problem but with the DE4. The TSE Tutorial  provided by Altera use the NiosII/s classic processor, but when it's upgraded to NiosII/f the same software application stall in PCS reset and MAC reset, so i made the configuration steps described on ug_ethernet.pdf (TSE User Guide) and neither worked. I'm trying to figure out where/what's the problem here too.
