Hi Community,

I was able to enable PPS on a selected GPIO as in the following discussion : Failed to request PPS GPIO

However, checking the dmesg, I found :

[345471.351791] pps pps0: capture assert seq #337025
[345471.351974] pps pps0: PPS_FETCH
[345471.351985] pps pps0: timeout 3.000000000
[345472.351753] pps pps0: PPS event at 1699933967.165083645

[345472.351914] pps pps0: PPS_FETCH
[345472.351922] pps pps0: timeout 3.000000000
[345473.351723] pps pps0: PPS event at 1699933968.165098333

[345473.351906] pps pps0: PPS_FETCH
[345473.351916] pps pps0: timeout 3.000000000

What could be the missing configuration to avoid above timeout, please ?

Meanwhile, in one of the comment of the following thread : Enable PSS on Jetson-GPIO Pin Header - #21 by KevinFFF

You could ignore the following messages.
[ 833.721567] pps pps1: PPS_FETCH
[ 833.721581] pps pps1: timeout 3.000000000

Hi khang.l4es,

Are you using the devkit or custom board fr Orin Nano?
What’s your Jetpack version in use?

Yes, it’s not the error so that you could ignore those timeout prints.
