Pixhawk4 Mini (holybro) failed to update IO fw

Unable to install ArduCopter on new Pixhawk 4 Mini.
Tried 2 boards just to make sure. Help :smile:

That’s probably Missionplanner?
The bootloader that ships with the PH4-mini doesn’t differentiate it from the PH4, so the way Missionplanner decides which firmware to load doesn’t work properly.
If you update to the ArduPilot bootloader for it, it’ll select the right firmware. Or you can use the custom firmware option.
FYI for Copter, PH4-Mini isn’t on a Stable release.

Hey, thank you so much!

How about this one?

No worries.
I quite like the PH4-Mini.
To see one in flight with ArduPilot, the mini-quad in this video: https://youtu.be/0s1ZBSB0tvM has one (no production on that vid, it’s just a flight record, but pretty cool nonetheless).

Brain fade on my part. Good find.
Rover/PH4-Mini is still in beta though.

I had the same problem with my PH4 mini, i downloaded the same file for plane, and custom installed, and it now works well but no beeps on start up? is it suppose to beep on start up?

Hi all~
i use the firmware is OK.

but i build APM Copter3.6.9 to pixhawk 4 mini.

Does anyone know of it ? thanks~

Try ./waf configure —board PH4-mini

i got it~ thank you!

I am still experiencing same error message despite following all of the above ideas. Tried MP and QGC for ArduCopter.

Make sure you have PH4-mini firmware (not fmuv5), then try updating the bootloader (ctrl-F in Missionplanner then click the button). Then reboot.

i updated the firmware on px4 mini to 4.0.5 using Qgroundcontrol but now the B/E light keeps blinking

Follow the steps below.

  1. install latest version using mission planner
  2. install coustum version using qgc

good luck

CAUTION: Be sure to wait until the install is complete.
