QGC cannot connect Snapdragon flight drone via serial to USB. And unable to upgrade the firmware. I am using latest QGC daily build. I tried 3.1.3 and 3.2.5 versions but no luck. Here are copied console logging and firmware.
Looks like it is showing up as an FTDI device. I don't know anything about the SnapDragon. Not sure how it is supposed to work. Hopefully some firmware folks can jump in.
