I chose the NOOBS (not the NOOBS LITE)
Raspberry Pi OS – Raspberry Pi
And set the parameters in pixhawk like the picture.
SERIAL2_PROTOCOL = 1
SERIAL2_BAUD = 921
LOG_BACKEND_TYPE = 3
But if I set “SERIAL2_BAUD = 921”, it’s will fail.
So I changed it to “SERIAL2_BAUD = 57”, and then it’s successful.
