Using pruDebug to modify register values?

I’ve been hacking away on the PRU and finding prudebug to be a fabulously useful tool for stepping through code.

Has anyone had any luck using the WR or WRD commands to modify data in the PRU registers?

I haven’t been able to figure out how the offsets are working. They don’t appear to be relating to the offsets in the TI published local memory map or the global memory map…

It also seems possible that this feature of prudebug is simply not working?

Any insights/guidance would be greatly appreciated.

Thanks,

Bill
