Hi All,

I’m running the latest betaflight, and just re flashed my mamba f405 mk2 to the latest firmware and my leds do not light up, if I re flash it with the legacy firmware the leds work but then I can’t set my motor output and a few other things the latest offers, if I use any other firmware later then the legacy only one led on each are lights up. Has any one experienced this ? Thanks

The Mamba F405 MK2 uses the FURYF4OSD Betaflight target, so make sure that is the one you are flashing to the FC and not one of the MAMBAF405US targets. Then when first connecting to the FC after flashing, make sure you click on the "Apply Custom Defaults" when that prompt appears.

Hi yes I’ve done all that, I’ve also tried different firmwares for the furyf40Sd only the legacy on makes all the led light up, if I use one from the middle of the options, I get one led on each arm blinking

Can you please run both the "dump" and "diff all" commands in the Betaflight Configurator CLI tab and copy/paste the results back here.

Please also post some good clear photos of the actual wiring so we can see how everything is wired up.

All of your settings look fine. Looking through the GitHub issues I see that someone opened an issue describing a similar (or the same) problem but they then closed the issue without saying why they had closed it. See the link below...

https://github.com/betaflight/betaflight/issues/10871

So it looks like there could well be a bug in the FURYF4OSD Betaflight target when using the LED_STRIP functionality. I would therefore suggest that you raise an issue for your problem on GitHub so that one of the Betaflight devs can look into it...
