I want to upgrade a CUAV Pixhack V3 board to the latest Ardupilot firmware.
The Board is unfortunately still on Nuttx OS with its original (old) bootloader.
The bootloader upgrade instructions on Ardupilot do not work (bootloader upgrade failed message in mission planner).
I assume the cause is that I did not put the board in DFU mode to allow a bootloader upgrade.
I can’t find documentation on the internet on how to put this board in DFU mode.
has anyone help on how to do that ?
For info this is my current config:
27/07/2020 10:55:02 : PX4v2 0029001F 3435510B 32363234
27/07/2020 10:55:02 : Frame: QUAD
27/07/2020 10:55:02 : PX4: de6b667d NuttX: 8c965992
27/07/2020 10:55:02 : APM:Copter V3.4.6 (e707341b
Im not using dfu mode coz i prefer use a jtag programmer for flash my boards.
You can try also in this way… just download from px4 firmware release the version px4fmuv3 and flash it using qgroundcontrol, after this you can check with MP but first flash it with ardupilot firmware
There is probably an issue with mission planner for this specific autopilot since it fails to put in bootloader mode (while it works with QGroundcontrol, proving the issue is not the board itself but rather an issue of mission planner not supporting it correctly for firmware upgrades)
