You can build the UF2 package to install on the Rasperberry Pi Pico using the instructions below, having first installed the SDK. Alternatively the package is built automatically by a Github Action and made available as an Artifact, which you can download and install by skipping directly to step 7.
- mkdir build
- cd build
- export PICO_SDK_PATH=/Users/sfegan/RaspberryPi/pico/pico-sdk
- cmake ..
- cd flasher
- make -j4
- Hold button on PICO and connect USB power until device mounted in mass-storage mode
- cp flasher.uf2 /Volumes/RPI-RP2
- screen /dev/tty.usbmodem141101
