NTP Server

[rjohnson]

I'm looking to build an ntp server using the OrangePi Zero 3 and I noticed there is no pps-gpio device tree overlay for the h616 chipset only the h5 chipset. Has anyone created a custom dt overlay? Thanks in advance.

Take this dts as reference, change the gpio to the opiz3 pin you want

Do you know how to use armbian-add-overlay?

Try this simple DTS file made by myself.
