## 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](https://comma.ai/shop/products/panda-paw) to go into DFU mode. If your device has an internal panda and none of the above works, try running `../tests/reflash_internal_panda.py`.
