https://docs.qmk.fm/#/flashing?id=raspberry-pi-RP2040-uf2

To flash:

• Clone https://github.com/qmk/qmk_firmware
• Make sure your QMK environment [is setup][qmkintro].
• Make sure halves are not connected together with TRRS cable.
• Connect one half to USB, flash the firmware (always follow the current instructions in the QMK documentation! The command might look something like this: qmk flash -kb sofle_choc -km default). Use the reset button to reset the keyboard when you are asked to in console.
• Connect the second half and flash it in the same way as the previous one.
• Disconnect the USB cable. Connect both halves together with TRRS cable.
• Connect USB cable to the left side.
• Enjoy!
