Programming

./flash.py        # flash application
./recover.py      # flash bootstub

Debugging

To print out the serial console from the STM32, run tests/debug_console.py

Troubleshooting

If your panda will not flash and green LED is on, use recover.py. If panda is blinking fast with green LED, use flash.py.

Otherwise if LED is off and panda can't be seen with lsusb command, use panda paw to go into DFU mode.

If your device has an internal panda and none of the above works, try running ../scripts/reflash_internal_panda.py.
