PX4 boot f\and firmware upgrade failure


(Phil) #1

I just bought a PX4. (Pixhawk 2.1 - px4v3)
When I power up my PX4 it goes through the orange LED’s and a few tones and then finishes with a tone like “bah bom” and LED’s off. No green.
I try plugging in to Mission Planner and it’s detected OK. when I hit connect
I try a firmware update using Arduplane v3.9.8. MP asks if it’s a “CubeBlack” (I assume it is because it has the black Cube on its back.) The flash appears to work ok but same issue “bah bom” tone and no green LED’s
Any ideas or help greatly appreciated as I am a total nube.
PS. Should I see it in Windows device manager?

Good day,
you can check in your device manager if your system recognized the rc.
Just flash the firmware again with thr last version of MP. In case it will not work again, this is the last step, just reflash the bootloader with a jtag programmer (nucleo board).

yeah I get the pixhawk show up in device manager as 'STMicroelectronics Virtual COM Port"
I’ve managed to Flash to the latest version successfully.
The green LEDs don’t show. Maybe I have a config issue.

You can try to update the bootloader with mission planner with the ctrl+f and reinstall the firmware again, but before proceed this just check on Mp parameters if the board its correct.
