View source for Flashing firmware on the Pi Pico

Very rudimentary for now - check https://www.youtube.com/watch?v=_bImqD-pQSA




== How to flash the pi pico from the raspberry pi using openocd ==
'''''Directly copied from a discord conversation'''''

use the .elf file if flashing via openocd or the uf2 file for flashing via usb mass storage
[[File:Pico update jumper.jpg|thumb|J22 jumpers to update pi pico by the raspberry pi]]


bridge the jumpers like on the right picture (you can leave them like this during normal operation, the idea is that instead of the jumpers you can use an external debugger on those pins as well)

on your raspi do<syntaxhighlight lang="shell">
cd open_mower_ros/utils/scripts/
sudo ./upload_firmware.sh /path/to/your/firmware.elf</syntaxhighlight>
