Hello @tom @Chad-Sweet 

Can PX4 firmware be uploaded on Flight Core v2 through VOXL2? While flashing SDK for VOXL2 can Flight core V2 be connected as external flight controller via UART and firmware be uploaded?

@Jetson-Nano It's not something we've tried. The easiest way is to load firmware through QGC.
