NIOSII - Week 8

For the Stratix board I had a problem with the IOR signal, when IORD_ALTERA_AVALON_LAN91C111_BSR(smsc->regbase) was called in a loop I would get
IOR signal always high which was not correct. So I rebuilt the project and got the IOR signal to alternating which is the correct signal.

Here is output of SSS.

dtrap - needs breakpoint is outputed because when reading for regbase the value is not 0x3300
when it is  AND with 0xFF00. I was able to get past this error by using a for loop and adding 1 to the regbase untill I get the correct value. Found that if you add 14 to thereg base you get the value you need. So I change the regoffset to 14 and I didn't get the dtrap - needs breakpoint error. Now I get a new error.

Figured out what the problem is, it is read at the wrong address.
