Right, and is that the only reason to have the simulator? I never really had to poke at the simulator. > some arm11 CPUs can use hardware to perform this > function, but i.MX31 can't. Likewise some armv4 and armv5 cores have singlestep hardware support in their EmbeddedICE modules. Does i.MX31 have one of the cores which extends Thumb with new instructions? I'm not sure they're all fully supported for use by the simulator. Worth looking at once you have the ARM instructions behaving. :) - Dave _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
