Following steps are tested on macOS 14.1:

1. Install homebrew like this
2. Install the correct compiler with brew install --cask gcc-arm-embedded
3. Install cmake brew install cmake
4. In the rp2040 directory create a new build directory with mkdir build
5. Change to that directory with cd build
6. Run the cmake file with cmake ../CMakeLists.txt
7. Make the smart lcc with make smart_lcc
8. Make the smart lcc combined with make smart_lcc_combined this should create the file: open-lcc/rp2040-bianca/build/smart_lcc_combined.uf2
9. Connect the open-lcc board to the debug board
10. Press the RP2040 Bootsel button while plugging the USB-cable into the RP2040 micro-USB port. The RP2040 should pop up as a drive.
11. Drop the smart_lcc_combined.uf2 file onto that drive

With dropping the uf2 file onto the RP2040 and rebooting, the firmware is installed and it should be running.
