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?
I tried both of them, both beta and stable version.
Additionally, every time updating, it takes different time to SOFTWARE_UPDATE to MAINTENANCE. Updating ends with different progress bar. Sometimes ends immediately after push update, or takes few seconds with almost 30% of progress bar. but never reached more than 30%.
I remember SW version was 1.5… before tried SW update. Now 0.0.0.
I tried SW update in order to use with PX4 autopilot FW. I did exactly same instruction in manual, i changed uavcan_node_id and connected to PX4 autopilot 1.11, However here3 not working properly (no lighting of here3). So I had tried to update SW of Here3.
I am currently having the same issue with the exact same setup… Can confirm that the firmware that came with the here 3 was not corrupted. The RTK worked on arrival but attempting to flash the latest firmware on it broke it - I have found no solution to this. Can someone help please?
