V3.4.5 - Motor #4 Anomaly: Fails to spin up when armed

It’s not uploading the firmware correctly then at a guess.

I generally load a plane firmware and straight back to copter if I get any funky behaviour.Don’t do it with props on as one motor will spin up quite fast when the plane firmware takes.The fast flashing blue LED should definitely calm down on completion like in the video.

It’s got to be worth a go.

Bootloader corrupt ?

Still struggling with this one.

It appears that the firmware is not flashing correctly as there are no start up tones and the onboard LED is not flashing correctly.This is a video of it’s behaviour during flashing.

Is it worth reflashing the bootloader would anyone think as this Pixhack unit is not responding to the usual handling of firmware.It is still not operating motor 4 on a quad firmware but I don’t think the firmware is taking correctly.

Should be alright if I follow the memory card method here for updating the bootloader?

Yay, Nay? Just need a little help with the NSH part, but I think I can manage the bootloader flash after that… If you guys think it’ll help that is.

Any thoughts here guys? I would really like to get this board in the air…
