I would like to thank Frank for his help. I am now getting the
clock tick and have console output working on the simulator.
Here are a couple of things that are important to know about
this simulator:
1. configure for tx39*-* otherwise the tx39 device support
and instruction set are not turned on. [The mips simulator
configuration is complicated because there are lots of
CPU models and ISA variations.]
2. The timer counts instructions.
Frank.. does the simulator have a mode for an R4000 class CPU
that supports the timer they have?
