Error when buliding PX4 firmware with some deactivated modules

65 views (last 30 days)
Dear all,
I am currently using simulink to impememt my filght controller into Pixhawk 6x. At the step of building PX4 firmware I followed this tutorial https://de.mathworks.com/help/uav/px4/ug/disable-control-modules.html to avoid flash memory overflow issues, since building a default PX4 firmware itself takes already 99% of the total flash usage.
I change the code
CONFIG_MODULES_MC_ATT_CONTROL=y
to
CONFIG_MODULES_MC_ATT_CONTROL=n
in the file default.px4board.original and resave it as a new file hil.px4board. in the same folder.
In the Hardware Setup screen I tried to build ths new firmware but there is then an Error in cmd window,saying:

Have you met this issue before and how did you solve it?
any suggestions or advices are welcome.
Thanks in advance.

After saving the file as "hil.px4board," did you select the newly saved px4board build target using the "custom px4board file" option?

thanks for reply. Yes I did use the new hil.px4board file as the "custom px4board file" when I build it at Modeling->Modeling Settings-> Hardware Impelementation -> Target hardware sources and Change Cmake configuration .

PX4 modules have interdependencies. So if you remove one module you have to remove the other as well. That is why the build is failing. To help you here, the support package already provides a few px4baord options that resolve these interdependencies. For example, if you plan to develop a multicopter, you can choose the 'px4_fmu-v6x_multicopter' px4board file and with this, you should not face any flash overflow issues.
Disabling Modules in PX4board Build Target File documentation page lists a set of modules that need to be disabled based on the airframe. You have to disable them as a set, you can't disable one alone as it will result in build failure.

I think the support package is doing some checks to validate correct cmake. To work this around can you try selecting the target as 'Px4 Pixhawk Series' in Simulink instead of 'PX4 Pixhawk 6x'? You might need to enter the correct COM port to upload the firmware in Simulink model configuration paramters (under Hardware implementation->Target hardware resources->Build Options).

Hey, thanks for reply. I used the 'px4_fmu-v6x_multicopter' px4board file. it takes about 95% of the flash memory but works well with my simulink model for now:) . I suppose I may still need to disable some module later if the simulink model becomes larger.
