MMDVM setup on a Pi

This is intended mostly as an aide-memoir to myself – your mileage may vary!

  • Image the Pi's SD card with Raspbian.
  • Mount the boot partition and edit cmdline.txt
    • Remove console=serial0,115200
    • Save
  • Edit config.txt and add the following to the end of the file:
    • This disables the Bluetooth module and enables the UART for MMDVM use.
  • Unmount the partitions and fit the SD card to the Pi – do not fit the MMDVM POG board yet!
  • Boot the Pi
  • When the Pi boots, log in (username pi, password raspberry)
  • Enter the following commands:
    • sudo systemctl disable serial-getty@ttyAMA0.service
      sudo systemctl disable hciuart
    • This disables the serial console and Bluetooth
  • Shut down the Pi and install the MMDVM POG board. Note: remove the 3.3V regulator if you're using the POG board as a HAT!
  • Boot the Pi and install the MMDVM software.
