I am looking for some help here, as I am currently stuck.
I have an i.MX6Q with a Linux kernel built using bitbake.
I have enabled PPS and GPIO support using the Linux menuconfig method.
I also have a uBlox GPS receiver powered and connected through GPIO pins.
I can see that there are PPS devices in my device tree and I can also manipulate and export GPIOs using sysfs. Also, I have installed ktimer to ensure that PPS is working and it looks fine here.
My question is, how can I tell LinuxPPS that I want to use an arbitrary GPIO as a PPS source coming from my GPS receiver?
Any help here would be greatly appreciated.
