Hi there!

We made extentions for ExternalAHRS. But according to code (AP_ExternalAHRS_config.h)

#define HAL_EXTERNAL_AHRS_ENABLED BOARD_FLASH_SIZE > 1024

this feature/module can build for drones with more then 1024 MB flash size.
We have MambaF405v2 drone with 1MB flash size.
Can we make build with ExternalAHRS for drone with 1 MB flash size?

Thank you!

Not, not easily. Get a F7 or H7 board.

Not easy means it іs possible.
We need this. Can you tell how can we do this?

Change the source code, throw away a lot of other features in order to have memory free for AP_ExternalAHRS. This can be done with compile options, this is the easy part.

Now change to code to activate AHRS and recompile it, keeping your fingers crossed that it will work later.
