The install firmware prompt mentioned in the instructions we got during previous updates, does not appear anymore. The disconnected MP almost immediately starts looking for a heartbeat and comports. When I connect the Pixhawk the ‘New Firmware-Rover 4.5.0 Pls upgrade’ message appears again.
Are the instructions on https://ardupilot.org/planner/docs/common-loading-firmware-onto-pixhawk.html not up-to-date?
I also tried the ’ Custom Firmware Build Server’ method. Same result.
