I'm trying to get the single step to work for the pru, my program only when I normally run it appears to only to the first action then halt, so i'm not sure whats going on so I figured I'd try to step through and watch the registers.
My program appears to run the first line then halt, and my program counter seems to just jump to a random location and halt, i think, I'm not quite positive what all the registers are in the CSL_PRUCORE_REGS structure
I'm fairly certin INTGPR0 is the r0, and my first 3 lines load r0,r1,r2,r30, and only r0 gets loaded.
