Have no control of pixhawk when starting up from the sd card

Dear all

After loading the Simulink model to the pixhawk using the awsome 'Embedded Coder Support Package for PX4 Autopilots', I couldn't arm the motors and start the flight, I'm sure that there is something missing in the 'rc.txt' file in the SD card, but I do not know how to fix that, looking for your help. I can't start anything. I have no control of the pixhawk. Also some parameters are not loaded.

thanks

here is my rc,txt:

#Copyright 2018 The MathWorks, Inc.

# This is the custom rc.txt which loads px4_simulink_app on start-up

usleep 1000

uorb start

usleep 1000

#nshterm /dev/ttyACM0 & #Disable the USB serial console

usleep 1000

tone_alarm start

usleep 3000

px4io start

gps start # #gps start -f Starts GPS driver and Fake a GPS signal (useful for testing)

usleep 1000

sh /etc/init.d/rc.sensors

usleep 1000

#Uncomment the below 2 lines to use LPE estimator

#attitude_estimator_q start

#local_position_estimator start

#Using EKF2 estimator by default as PX4 does build LPE on px4fmu-v2 due to a limited flash.

ekf2 start

usleep 1000

mtd start

usleep 1000

param load /fs/mtd_params

usleep 1000

rgbled start

usleep 1000

fmu mode_pwm # This is required for AUX PWM channels

usleep 1000

#......... arming ....

mavlink start -d /dev/ttyACM0 -m config –x

px4_simulink_app start

nshterm /dev/ttyS6 & #this will make ttyS6 the serial console

mavlink boot_complete

#exit #4-Jan-2019

you understand that you cant arm it with QGC?

your simulink code replaces the logic(arm sequence and alot more) of the px4 base software

if you want pixhawk to do anything , you do it by writing and then building your logic into the pixhawk

1. did you try the example : https://www.mathworks.com/help/supportpkg/px4/ref/pwm-getting-started-px4.html '?
2. did you try the aux ports?
3. did you provide the pixhawk rail pins and the esc the correct voltage?
4. try with simple servo

from experience , it works

Hi,

try 'px4io safety_off' in the nsh or rc.txt. Maybe its just in save mode...

Best, Sebastian
