updating time to GPS time on IMXQXP

[sistlajr6]

Hi ,

I am running demo linux images from NXP on the iMX8QXP. I am able to connect a GPS receiver and get the nmea data by accessing /dev/ttyACM3 ( since its a usb based GPS reciever) . Now i am trying to get the date and time updated to the GPS time. How can I achieve this on the imx demo image.

Regards,
Sistla.

Hi Sanket,

I am trying to use a USB based GPS module, on Ubuntu i am able to the opensource libraries to read the time and data , lat and long and all the data. 

On iMX i am able to use /dev/ttyACM* to read the NMEA data. But i am looking at the yacto build if there is any publicly available libraries that i can use to nmea data from this port  just like gpsmon or some

Hi @sistlajr6 

I hope you are doing well

To read NMEA data one can use 'gpsd' related packages in meta-openembedded layer.

One can add the below packages in conf/local.conf and check the recipe build using bitbake.

" gpsd gps-utils libgps gpsd-gpsctl"

bitbake gpsd

Thanks & Regards
