I just fixed this problem by installing PX4-Autopilot firmware to the Linux home directory(not windows directory) and not executing bash ./ubuntu.sh command.

Run the following command in the MATLAB command Window. This will unblock you from the error you are facing

setpref('MW_PX4_Build','FullFirmwareBuild',true)

We are working on a fix for this issue

Hello,

I have another problem, that is QGroundControl doesn't recognize a pixhawk board when px4 firmware was built from MATLAB(version 1.14.0) and I found that Mavlink messages can not be received like below.

How can I fix this problem?
