Hello everyone,
After uploading an original version of PX4 in my Pixhawk 1 (through QGroundControl, so no modification on the code), I realized that even though I was armed, my PWM outputs were on their failsafe value.
I tried uploading PX4 through QGroundControl to a Pixhawk 3 Pro (a new one, taken out of the box only for that) and the problem stays the same.
I then took a look at what “px4io status” would give me and here it is :

As you can see, I get the FM_LOST alarm and can’t get why this happens ! Also, I have the Amer LED blink at 4Hz on the IO side. Any help would be really appreciated as I can’t seem to find any explanation !
Thanks in advance !
