Hi, 

I am using the frSky xsrf4po combo of PDB, FC, and Receiver all in one.  Using Betaflight the version used on the flight controller said omnibus.  I flashed the firmware to the latest version of Omnibus.  My question is should I have flashed the Frsky firmware or did I do it correctly using omnibus.   Thank you.

The FrSky XSRF4PO fight controller uses the OMNIBUSF4 target firmware. Just make sure you use the OMNIBUSF4 target and NOT the OMNIBUS target (without F4 on the end).

I will double check but am pretty sure I used the OMNIBUSF4. I appreciate your help. Thank you.

According to the manual you should use the FRSKY F4 target.

Good catch.

It seems that the XSRF4PO comes pre-flashed with the OMNIBUSF4 firmware for whatever reason but there does indeed appear to be an FRSKYF4 target Betaflight firmware available. Maybe the FRSKYF4 target is based off the OMNIBUSF4 build with a few minor config changes. I've not compared the target build files to check. Still, it is always best to use dedicated target firmware for a board if one exists.
