Hello to you all. I bought 2 HEREPro GPS’s to use them for gps-yaw. As I was trying to implent this for days, I did a firmware update to both modules through the mission planner app. I rebooted the whole system and one of the HEREPro’s did not boot and is not booting since then. I use lab supply voltage 12V to both modules and xt30 connectors to prevent reverse polarity issues. The only thing that may happened is something with the firmware. Does anybody have an idea how to fix this?
