Thanks for replying, @Amynannan
I am currently studying the modules mc_att_control and mc_pos_control, I want to design a controller, matlab was an option but when I compiled the example px4demo_attitude_system.slx, my pixhawk did not work properly, the lpe modules and attitude estimator disappeared, I need those modules because my pixhawk uses a mocap system.
Why did I get that error?
I think it’s due to the reboot system
