I am experiencing firmware issues with the Holybro Pixhawk 4 Mini.
The Pixhawk 4 Mini comes pre-installed with PX4 v1.8.0 dev according to the product page:
Out of the box it functions fine, but when I updated the firmware to v1.8.2 stable I get the error “failed to communicate with IO: abort”. As a result, none of the external IO devices work properly and I get the 5 extended beeps from the buzzer that signifies an IO problem. However, when I changed the firmware to the latest developer (master) build, the IO works fine. I also tried building v1.8.0 stable from from github, but I get the same IO error when loading it onto the board.
Does anybody know why the IO on the Pixhawk 4 Mini works on the developer build, but not on the stable builds?
I have conducted testing with the latest developer build through QGC, but it is too unreliable to use. I really need a stable release for my current project.
Any help is much appreciated.
