PX4 1.9 - Pixhawk 4 - Parameters are missing from firmware

#1

Hello, I recently upgraded a Pixhawk 4 that had PX4 version 1.8 on it to version 1.9. After doing this I can no longer set the airframe type. I am getting the following error in QGroundControl. "Parameters are missing from firmware. You may be running a version of firmware QGC does not work correctly with or your firmware has a bug in it. Missing params: -1:SYS_AUTOSTART, -1:SYS_AUTOCONFIG.

I upgraded to the latest version of QGroundControl and verifyied that those configuration items are in the QGroundControl configuration parameters. I am suspecting it is the PX4 v1.9 firmware.

Has anyone else seen an issue like this? Any help would be appreciated.

I recommend to reset all parameters and do a fresh setup. The screenshots below show how to do that:

Thanks for the reply, will try that if it happens again, but it is fixed now.

I am not exactly sure what the issue was, but it is working now. Potential resolution 1) Upgraded to 1.9.1 and 2) may have had a bad pixhawk as I was seeing a mag calibration and failure to arm issues also. (new pixhawk resolved those issues)
