Programming and Debugging

Flashing

To flash, disable the existing driver that ties up the serial port and use the customized BSL Python script.

  1. Ensure the bcfserial or gb-beagleplay driver isn’t blocking the serial port. This can be done by loading :file: /overlays/k3-am625-beagleplay-bcfserial-no-firmware.dtbo or selecting uboot entry which disables bcfserial/gb-beagleplay.

  2. Now reboot the board.

    sudo shutdown -r now

  3. Install CC1352-flasher if not already installed

    if ! command -v cc1352_flasher &> /dev/null; then pip install cc1352-flasher; fi

  4. Flash the CC1352P7

    west flash

Debugging

For debugging, you can use the serial port or JTAG. You can use OpenOCD over the Tag-Connect header on the board.

  • Tagconnect JTAG
