Hi Timothy, i think i found the problem... the pinmux was still not being setup properly.. I just pushed a config-pin update for the Blue.. sudo apt update sudo apt upgrade sudo apt install tio i picked up a uBlox PAM-7Q module, it's only 3.3v so i have it hooked up to UT1, i know your on GPS connector (5.0v) So on bootup we see: (UT1) debian@beaglebone:~$ config-pin -q P9.24 P9_24 Mode: none debian@beaglebone:~$ config-pin -q P9.26 P9_26 Mode: none and (GPS) debian@beaglebone:~$ config-pin -q P9.21 P9_21 Mode: none debian@beaglebone:~$ config-pin -q P9.22 P9_22 Mode: none So by default, using tio: debian@beaglebone:~$ tio -b 9600 /dev/ttyS1 [tio 16:32:20] tio v1.20 [tio 16:32:20] Press ctrl-t q to quit [tio 16:32:20] Connected <nothing> If i switch P9.24/P9.26 to uart: debian@beaglebone:~$ config-pin P9.24 uart debian@beaglebone:~$ config-pin P9.26 uart debian@beaglebone:~$ config-pin -q P9.24 P9_24 Mode: uart debian@beaglebone:~$ config-pin -q P9.26 P9_26 Mode: uart then fire up tio: debian@beaglebone:~$ tio -b 9600 /dev/ttyS1 [tio 16:33:08] tio v1.20 [tio 16:33:08] Press ctrl-t q to quit [tio 16:33:08] Connected W$GPRMC,163309.00,V,,,,,,,300617,,,N*70 $GPVTG,,,,,,,,,N*30 $GPGGA,163309.00,,,,,0,00,99.99,,,,,,*68 $GPGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*30 $GPGSV,3,1,11,01,31,123,,07,46,149,17,08,32,052,17,11,50,107,19*74 $GPGSV,3,2,11,13,31,299,21,15,08,327,,17,26,215,,19,02,218,*76 $GPGSV,3,3,11,27,00,046,,28,64,291,,30,79,211,23*42 $GPGLL,,,,,163309.00,V,N*44 $GPRMC,163310.00,V,,,,,,,300617,,,N*78 In your case run: debian@beaglebone:~$ config-pin P9.21 uart debian@beaglebone:~$ config-pin P9.22 uart debian@beaglebone:~$ tio -b 9600 /dev/ttyS2 and see that happens (9600 might not be the baud) I've added both UT1 and GPS info here: https://github.com/beagleboard/beaglebone-blue/wiki/Pinouts Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
