I am trying to run HITL experiment with Pixhawk 4. I am trying to use Gazebo 7 and Qgroundcontrol for that.
B/E LED of I/O is amber and blinking with the latest firmware. There is so bootloader.txt in the SD file either. The issue persists with older versions (1.9.0 and 1.7.0) of firmware too.
What is probable cause for this issue to happen? Also, what is the possible solution for this issue?
Thanks in advance!
