How to configure linux_sbus driver for PPM RC receivers

Hello, firstly I would like to say that we are trying to successfully run PX4 on a Microzed board with an ad-hoc additional board with sensor (IMU, GNSS, barometer, magnetometer). We thanks Aerotenna for the work done for porting PX4 to a ZYNQ processor.

About my question, I would like to know if the linux_sbus driver running on PX4 can automatically detect if the RC receiver signal is SBUS or PPM, or if it must be set for PPM RC receivers at compilation time. I understand that the linux_sbus driver supports both standards.

We have a PPM RC receiver and is not working. We have connected the PPM signal to the RX input of an UARTLITE IP core. We have tried to calibrate the RC transmitter using QGroundControl but QGC does not detect an RC signal.

I really appreciate any help you can provide.

Regards.
