[gpsd-users] gps source detection problem (GNS1301 receiver, serial port, gpsd 3.15 and current git, ARM cortex A8)

[Arndt Kritzner]

Hello,

with a board with AM335x-CPU I I cannot get gpsd to work, although NMEA 
telegrams are received via the serial port. If I
don't use a fixed baudrate gpsd loops infinitely trough alle possible baudrate 
settings. Gpsd was built in a buildroot
configuration (Versions 3.15 and current GIT). The serial port already has 
before gpsd starts the correct settings, but
gpsd has another opinion.
Anyone any ideas to fix this?

Thanks in advance
Arndt
