Hmm, so you are on a RasPi.  What header pin are you on?  What does
your /boot/config.txt look like?  Here is mine:

    ~ # cat /boot/config.txt 
    # Disable Bluetooth so serial-tty speed is no longer tied to CPU speed
    dtoverlay=pi3-miniuart-bt

    # Uptraonics on gpio 18
    dtoverlay=pps-gpio,gpiopin=18

    kernel=zImage-4.9.34.img

    # don't need the gpu mem
    gpu_mem=16
    no_hz=off

Do you have pps-gpio compiled into your kernel?  Or is it a kernel module
you know is loaded?

And other things to try as well.  Maybe try a diff gpio pin?
