prudebug

TI Programmable Real-Time Unit Subsystem (PRUSS) / PRU debugger. Provides the ability to load binaries in the PRUs, display instruction and data memory, disassemble instruction memory, start/stop the PRU, and has a pseudo-run feature that auto-single-steps through the program while providing breakpoints and variable watches. Prudebug supports both PRUSSv1 and v2. It can map PRU memory through both /dev/mem and UIO device driver (command line option).

Features

Load binaries into PRU
Display instruction and data memory space on PRUs
Disassemble instruction memory space
Start and halt PRU
Single step PRU
Pseudo-run (auto-single-step) mode supporting break on variable and watches
Very limited dependencies - just standard library and /dev/mem device
Could probably be easily ported to systems other than embedded Linux
