Wired up XM+ receiver with Tyro79's FC had some problems binding XM+ with jumper T-lite, so I flashed XM+ to pre accst2 software and it bounded. Now the problem is no receiver input is shown under betaflight. CLI get status returns RX Loss. I have tried all the following combinations flashing FC with latest, old (2019) and latest Experimental software. While checking voltage (0.7-2.7v) bridged signal wire to RX1,RX2, RC and those 3 pads destined for ppm or SBUS selection ( [sbus] [ blank] [ppm] where SBUS is bridged with the blank pad).( Have no idea if FC recognises receiver signal from all these UARTs after boot sequence) also each time switched between UART 1 signal RX and UART 2. Under receiver configuration I tried Fport, SBUS and IBUS I also inverted serial RX and uninverted. I tried different receiver That's quite a bit of combinations and I never received channel input in betaflight. The only time I got something is when I chose Spektrum 2048 and 1024. I have no idea if any of those random inputs correspondend to my transmitter. Jumper T-lite is also showing that it's outputting signal to the right channels. Any Ideas what I could try or is the FC dead, although I was super careful with it.
