Testing GPS can be done using a daemon, gpsd, and console application, cgps, which is included in the gps-utils package.
Installing Packages
Here are two methods for installing gpsd and gps-utils.
Network Install
If your Overo is connected to the Internet installation is very simple. Very simple.
# opkg update # opkg download gpsd # opkg download gps-utils # opkg install gpsd # opkg install gps-utils
Offline Install
If your Overo doesn't have an Internet connection, the easiest way to install the required GPS packages is by including them in an image.
$ cd ~/overo-oe/org.openembedded.dev/recipes/images/ $ cp omap3-console-image.bb omap3-gps-image.bb $ nano omap3-gps-image.bb
Add the packages gpsd and gps-utils to the TOOLS_INSTALL section.
$ bitbake omap3-gps-image
Create a bootable microSD with the resulting image.
Configuration
gpsd will start automatically when you boot, however you will need to tell it what serial port the device is connected to.
# killall gpsd # gpsd /dev/ttyS0
You can change the ${GPS_DEV} variable in the /etc/default/gpsd to /dev/ttyS0 so it will work automatically on boot.
Test
# cgps
