I don't know of a way to debug the PRU.

There hardware support for debugging the CPU in the AM335x, and a few programs that have support for debugging. Nothing as fancy as gdb, but it can be helpful. I mostly use the pru_debug setup from Machinekit, which basically allows viewing register contents while single-stepping and pausing (but no breakpoints).

The programs I know about are listed here:

...the list is a bit dated, if anyone knows of other tools (or a better list), let me know.
