I had a really nice friend give me a Turnigy 9XR with a FrSky DJT module with the separate telemetry screen. I was wondering, which firmware is best to use on it, OpenTX or ER9X? It has the ER9X r803 firware on it now. I tried hooking it up to the OpenTX 2.1.3 Companion software with a USBasp adapter, but even with the 9XR selected in the settings (with or without M128 chip) it doesn't seem to flash the firmware correctly. It goes through the read process, but never writes to it. Does the USBasp driver work ok with Windows 10?
