If your system lacks the systemctl command, use any equivalent command that works on your system to disable services. You can add yourself to this group as below: In order for Betaflight configurator to be able to access serial ports, your account needs to be in the dialout group. You need a proper USB cable to connect your board to the Betaflight Configurator. These will power up the board, so the leds light up, but the host computer will not react to the device at all. If you see no signs of life on your host computer when you plug in your board, check your cable with your mobile phone or some other USB device - some charging cables have only the power pins connected. The baudrate checkbox is ignored as it has no relevance to USB. The Full chip erase checkbox operates as normal. The 'No reboot sequence' checkbox has no effect as the device will automatically be detected when already in bootloader mode (a DFU device will appear in the connect dropdown if this is the case). The standard flashing procedure should work successfully with the caveat of some platform specific problems as noted below. This is a straightforward process in Configurator versions 0.67 and newer. Some newer boards with full USB support must be flashed in USB DFU mode.
