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? > - FChE -- Joel Sherrill, Ph.D. Director of Research & Development joel@OARcorp.com On-Line Applications Research Ask me about RTEMS: a free RTOS Huntsville AL 35805 Support Available (256) 722-9985 ------ Want more information?
