I.MX6Q SABRE AUTOMATIVE GPS PPS CONNECTION

Dear All,

I have I.MX6Q Sabre Automative Infoteinment card. It has UART, power and some other signals on CN1 connector on its base board. I want to connect a GPS device which has PPS signal to it. Where should I connect PPS signal?

RS232 DCD and DTR signals do not exist on this connector.

There is only "GPS_INTERR_B" signal which might be suitable. What is this signal's function?

Thank you,

Dear Victor,

Thank you so much,

Since I do not know very much about Linux kernel, I need additional information. How can I use this code? Should it be patched to the kernel?
