VisualPRU is a minimal browser-based editor and debugger for the Beaglebone PRUs. The app runs from a local server on the Beaglebone and is accessed by connecting the Beaglebone to your computer via USB and navigating your browser to 192.168.7.2:3333. You can also connect via wireless or ethernet with configuration of a static ip.

Internally,The hardware is accessed by twiddling bits in memory-mapped /dev/mem . Assembly programs are compiled using TI's open-source pasm library.

Screenshot

• The Header allows you to choose which PRU you are targeting and shows their current status. If you're working on an application where the PRUs collaborate, it's possible to trigger a program on one PRU and debug the other PRU as they interact.
• Column 1 shows the editor view. You can add as many files as you want and include them in your main program(e.g. for header files and macro definitions).
• Column 2 shows the compiler view. It shows the output from the TI PASM compiler and allows you to step through your compiled code or run it full-speed.
• Column 3 shows the memory view. It allows you to look at the values of all the general purpose registers.

Install python if necessary, then:

pip install bottle
pip install gevent-websocket

cd /home
git clone https://github.com/mmcdan/visualpru.git

Finally, download pasm, run the linuxbuild script, and put the resulting executable in /usr/local/bin (or another system-wide binary location)

Just go into the VisualPRU directory and type python visualpru.py, then navigate to 192.168.7.2:3333 with your browser! To stop the program, use CTRL-C.

• Transition from /dev/mem to UIO
• Add the ability to load existing source files
• Highlight errors in the editor view
• Allow the user to modify memory registers
• Show Data RAM, Scratchpad RAM, and DDR RAM chunk in memory view
• Add better error-handling for edge cases
• Add unit tests

• Web interface layout is compressed when using Internet Explorer
