Unable to achieve PPS with Jetpack 5.0.2

Finally managed to get the /dev/pps1 to show.

The two things I did:

  1. Set CONFIG_PPS_CLIENT_GPIO=m, as mentioned in the thread linked by @JerryChang
  2. Make sure that it is set in tegra_defconfig as well
  3. Build, and manually copy the tegra194-p3668-0000-p3509-0000.dtb to the NX’s /boot/dtb and replace the existing file

Now, after adding the PPS GPIO with insmod, /dev/pps1 is shown.

Thanks for the help!
