Hello,
I have two Pixhawks 4, one of them fine because I see the following led configuration:
I/O PWR: green on
I/O B/E: blinking orange
I/O ACT: blinking blue
FMU PWR: green on
FMU B/E: off
FMU ACT: blinking blue
but for the second Pixhawk 4:
I/O PWR: green on
I/O B/E: off
I/O ACT: off
FMU PWR: green on
FMU B/E: off
FMU ACT: blinking blue
I have access with both Pixhawks using QGroundControl, all parameters reset to firmware default, and firmware updated to latest version.
In the “faulty” (the second one) Pixhawk I/O reset push-button has been tried, but no success.
Why could be the reason the I/O controller is not running?
Thanks in advance.
