I have tried recompiling the kernel from scratch, no avail, redoing the file system, same thing.

I reduced to the very basic components and see the same results.

I have configured /etc/rc to do nothing with ehternet on power up init.

After the board comes up, I connect (nios2-terminal) see all the messages go by, and as soon as I enter "dhcpcd -NRY&" at the console, I get these messages.

Please lend a hand to a fellow engineer,

Thanks,

Carlos

I have found it!

Even though the description for interrupt "0" says that it can be used for the system timer it is not. As a general rule you should never use interrupt "0" for anything.

I did this and the problem was resolved immediately.

Great!

I will update the wiki about the irq 0.

Could you write a howto about dhcpcd on the wiki? It would be very helpful.
