Can the jetson nano enable PPS as raspberry pi?
I work with the jetson nano recently and try to synchronize it with GPS. I know the raspberry pi can easily set pin 18 as PPS pin and then do synchronization with GPS.
Any idea to do the same thing on jetson nano?
I checked it, but I believe there should be a easier way to achieve it. The chip after TX1 can support the PPS.
I followed https://devtalk.nvidia.com/default/topic/1035352/pps-drivers-not-installing/, and enable the pps from the kernel, but it shows the time out every time when I
sudo ppstest /dev/pps0
For more detail, I added the pps device to the device tree (pin 18):
gpios = <&gpio TEGRA_GPIO(B, 7) 0>;
compatible = "pps-gpio";
status = "okay";
I want to know is there any easier way to make it work?
I think I fix this issue because it’s physical pin 18 and gpio15 (Sysfs GPIO) and I use the wrong pin to get PPS signal.
