Found that dmesg
reports
Starting GPS Port on /dev/ttyS3
Conflicting config for /dev/ttyS3
This is apparently because SEP_PORT1_CFG
is also set to GPS 1 by default so it conflicts with GPS_1_CONFIG
.
Solution for you @sssagara is to set SEP_PORT1_CFG
to "disabled" and reboot.
This issue has been mentioned on Discussion Forum for PX4, Pixhawk, QGroundControl, MAVSDK, MAVLink. There might be relevant details there:

Yes! That solved it! Thank you for the help and really appreciate the quick reply!
Describe the bug
GPS module (Holybro Neo-M8N) doesn't seem to be recognized when PixRacer Pro is flashed to v1.15.0. GPS Status does not show up as valid in QGC main page and GPS_RAW_INT message is also not present in MAVLink Inspector.
When flashed with v1.14.3 with the exact same setup and params, GPS module is immediately recognized and GPS status and GPS_RAW_INT message are present.
To Reproduce
Expected behavior
Expected to see GPS status on QGC main page and GPS_RAW_INT message in MAVLink Inspector

How are the different components wired up (including port information)
Additional context
When flashed with v1.14.4 with the setup and params unchanged and the same, the GPS module is immediately recognized after flashing. Tried figuring out if the GPS module was faulty by testing it with a Pixhawk 4. When Pixhawk 4 is flashed with either v1.14.4 or v1.15.0, the same GPS module is immediately recognized and GPS_RAW_INT messages present in MAVLink Inspector
v1.14.4 PixRacer Pro
