Px4-autopilot: Unable to add new airframe for FMU-v5

[themcfadden]

Describe the bug
Following the instructions outlined in https://dev.px4.io/master/en/airframes/adding_a_new_frame.html, I am unable to add a new airframe under FMU-v5. Everything builds with no issues, but nothing shows up in QGC and the airframes.xml file in the build directory is not updated.

I am able to successfully do it under the FMU-v4 build.

A couple notes:

• The 4250_Teal, and others are not showing up in my fmu-v5 build. The airframes are there and listed in CMakeLists.txt, but are not part of the build output.
• Even commenting out something in airframes/CMakeLists.txt does not change anything.
• I believe the official FW release has the Teal and other missing airframes.

To Reproduce
Steps to reproduce the behavior:

1. Update or create a new airframe in Firmware/ROMFS/px4fmu_common/init.d/airframes/ as per instructions pointed to above.
2. make px4_fmu-v5
3. Check Firmware/build/px4_fmu-v5_default/airframes.xml and observe no changes.

Expected behavior
Airframe is created as in other targets.

I haven't tried this, but in step 3, shouldn't you be checking the v5 path? Firmware/build/px4_fmu-v5_default/airframes.xml

Yes, correct. px4_fmu-v4_default is a cut and paste error.
I updated the original post with px4_fmu-v5_default in the path.

Are you sure the ID you attributed to the new config is unused?

And you don't have an exclude like here?

Check what @julianoes just said. I literally just copied the 4250_teal airframe file into a 4251_teal, deleted that line and it's building on v5.

[themcfadden]

Yep, that's it. Thanks for the quick response!

Just curious, how is the airframe.xml file generated? Is there a script I can review?
