To read the NMEA messages from the GPS Module of VIBE :
- Enable UART4 (/dev/ttyO4) in device tree kernel.
#cd /lib/firmware #echo BB-UART4 > /sys/devices/bone_capemgr.9/slots
- You can read the slots or use dmesg to see that UART4 has been enabled.
#cat /sys/devices/bone_capemgr.9/slots
- Output will be like this :
0: 54:PF--- 1: 55:PF--- 2: 56:PF--- 3: 57:PF--- 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G 5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI 7: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART4
- Install Minicom or use the following commands to see NMEA messages
#apt-get install minicom #minicom –s (port settings /dev/ttyO4 19200 8N1)
OR
#stty –F /dev/ttyO4 19200 raw #cat /dev/ttyO4
