How to find Generic Quadplane airframe type with Pixhawk 2.4.8


I have a new Pixhawk 2.4.8 with FMUv2 firmware that I’d like to use for a VTOL Quadplane project. Anyways, after I install the PX4 firmware using qgroundcontrol, in the airframe setup I cannot find any VTOL airframe types.

I understand that the possible fix would be to update the bootloader to FMUv3? Bootloader Update | PX4 User Guide (v1.14)

However I cannot find the SYS_BL_UPDATE parameter.

Would be glad of any assistance in how to find this parameter or if there’s another way to enable VTOL airframe types for the Pixhawk 2.4.8!

Figured this out! Once I installed older PX4 version (1.13) FMUv2, I was then able to access the SYS_BL_UPDATE parameter and follow the rest of the instructions

Hmmm, so when you installed PX4 v1.13 you see SYS_BL_UPDATE but not when you installed the PX4 development firmware (“Master” in qgc, but actually the build from main branch). Is that right?

FWIW Pixhawk 2.4.8 is very very old technology and even running FMU v3 isn’t great. In particular you might find some code isn’t installed by default.

Yes, that’s right. As I’m new to PX4, I’m planning on using the 2.4.8 to learn about PX4 and autonomous drones in general and then move on to some of the newer, more expensive flight controllers

Thanks @josh8991

A little searching shows this is a known issue rc.board_bootloader_upgrade isn't compiled in. No SYS_BL_UPDATE · Issue #20592 · PX4/PX4-Autopilot · GitHub
