Jumper R8 Receiver With BeagleBone Blue

I am trying to get Jumper R8 receiver work with BeagleBone Blue Sbus but spent hours with no success, here are the things I tried,

  1. BBBlue works with any other receiver like (FrSky XM Plus Mini, X8R, R9 Stab, R9 mini) all these receivers work perfectly with BBBlue SBus.
  2. The receiver (Jumper R8) works with other flight controller (beta flight).
  3. I tried inverting the Sbus output from the receiver (to see if it is coming out un-inverted) but it did not work.

I ran also this command: cat /sys/devices/platform/ocp/ocp:P8_15_pinmux/state
and the output is: pruecapin_pu

I am not sure what could be the problem, any body faced the same thing?
