Troubleshooting PX4 Firmware Build Failure Due to Flash Memory Overflow on the Hardware

Description

If you are using the default PX4 board build target file, such as cubepilot_cubeorange_default, the build might fail due to flash memory overflow on the hardware with the following error message.

The reason for this issue is because the source code size increases with PX4 firmware v1.14. If all modules are enabled for build, it might result in flash memory overflow on the hardware.

Action

To troubleshoot the issue disable some modules from the default px4 board build target file. For example, if you are designing a Multicopter, consider removing fixed-wing controller modules and vice versa.

For some autopilots, the Multicopter, fixed-wing, and VTOL controllers are already selectively disabled, and variants of the default PX4 board build target files are available. If there is a Multicopter or fixed-wing variant of the PX4 board build target file for the PX4 autopilot you are using, choose that file instead of the default one.

For example, if you are using Cube Orange and facing build failure due to flash memory overflow on the hardware with the cubepilot_cubeorange_default PX4 board build target file, consider using cubepilot_cubeorange_multicopter for designing multicopter, cubepilot_cubeorange_fixedwing for -wing and cubepilot_cubeorange _VTOL for VTOL airframe.

If no Multicopter, fixed-wing, or VTOL variants exist for the autopilot you are using, manually create them by editing the default PX4 board build target file. For more information, see Disabling Modules in PX4board Build Target File.
