Pixhawk 1 Current Firmware Download

I have an old pixhawk 1 i built a plane with it in 2016, is it possible that i can download the current firmware version on it and upload it to another pixhawk 1 ?

No. And why would you want to?

because the person that helped me build that rc plane im not in contact with him anymore, and he built a custom firmware on that pixhawk, thats why i wanted to see if i can download the firmware off it.

Use the Parameters and as a starting point and the latest stable version.

Note: Well, the parameters have changed quite a bit since 2016, even the parameters names. What version was the custom based from?

when i start it with mission planner , this what pops up on the messages

AP_03.0030.1

PX4v2 001A002F 3335510F 32383336

That is running PX4 firmware, not ArduPlane firmware.
You are in the wrong support forum.

Thank you, went to the correct support forum. my apologies

i went to pixhawk forums, and they said this is ardupilot firmware, just want to confirm

Looks like some ancient version Ardupilot. Are there any log files stored? Post a link to one if so. Or, just try loading the current Stable fmuv3 or Pixhawk1 firmware.

@dkemxr he wants to download the old FW from the FC, not upload a new version to the FC.

@amilcarlucas Yes, I saw his initial request. I suppose I was suggesting to abandon that plan and simply update to latest Stable and get to configuring!
