I guess you'll have to halt the processor in some way, but I don't know how to do that either.
A simple way that fits you needs of configuring the MAC + PHY is to add a "JTAG to Avalon Master Bridge" component.
It will also show up in the system console like the processor and you can start writing to/reading from your system without halting anything.
Please find below a complete walkthrough:
set path 0]
Be sure you'll catch the JTAG Bridge and not the NIOS. Maybe you'll have to insert a 1 instead of a 0.
If you want to be sure, remove the NIOS completely :D.
open_service master $path
This will link the System Console to your master.
You could perform
is_service_open master $path
to see wether it worked (=1) or not (=0).
Now you're ready to go with
master_write_32 $path 0x12345678 0xdeadbeef
and
master_read_32 $path 0x12345678 1
Hope that helped :)
