I’m trying to upgrade here3 gps firmware bia doc, But It does not work.
Mission Planner version : 1.3.74.1 build 1.3.7747.6708 (latest beta version)
Holybro Pixhawk 4
used latest ardupilot firmware.
After tried to update, SW version is set to 0.0.0 / SW CRC 0
when connected, mode : maintenance, health : critical.
However, after pushing, update beta, done fw downloading, it starts update with
mode :SOFTWARE_UPDATE and HEALTH OK.
but after few seconds, FAIL, return to MAINTENANCE and health CRITICAL.
I tried multiple times with different computer and reconnecting multiple times, but no better results.
Is there other way to update firmware?
And where can I get help?
