    Hy, has anyone used the 1PPS signal given from a gps module to update the time in udoobuntu (1 or 2)? Where I have to connect that signal?
    Thanks a lot! :)

    I dont know the best answer but, if i were you,
    1- First option is writing a driver and compiling kernel with resources. It is impossible for me for now.
    2- I would use arduino due pins on the atsam3x8e chip to communicate with GPS. Firstly program the due, after getting messages from gps, you can send the data with Serial1 uart to imx6 side. For example in putty, we use serial connection with a specific baud rate. In windows com ports used. This example almost same with this process. A python script which reads serial and sets the time may be easiest way(after sending messages from due to imx6 uart.)
