HackRF - portapack-mayhem/mayhem-firmware GitHub Wiki

The Button 'HackRF' from the main menu enables the HackRF Mode. You can use your assembled PortaPack and HackRF with Mayhem Firmware, just as you are using a standalone HackRF Board, without further modification or flashing.

The PortaPack input (dial, buttons, touchscreen, ...) are not working in this mode. The Display will show a plain block diagram at start, and add some values after connect to a SDR application. See Pictures below. The hackrf_info still shows the firmware version of the Mayhem firmware:
