Right now i have PPS Support enabled in kernel config but am still unable to get a PPS out of the device using ppstest on /dev/pps0 which seems to be connected to /dev/ptp0 (Connection timed out with error -1). Looking around at the documentation, there seems to be a mentioning of pins AE1 and AF3 that support TSEC_1588_PULSE_OUT1 and TSEC_1588_PULSE_OUT2 signals respectively.</P><P></P><P>My question is what settings would I need to change in my kernel configuration to change the behavior of these pins to output the pulse out signals?&nbsp;</P><P></P><P>My end goal is to send out a 1 pps whenever 1 second passes on the system clock which I have sync with a master using PTP.</P><P></P><P>Any help would be greatly appreciated!</P></BODY></HTML> Mon, 24 Feb 2020 19:15:04 GMT https://community.nxp.com/t5/Layerscape/Setup-LS1046ARDB-Board-with-1588-PPS-Out/m-p/1008214#M5380 kien_tran 2020-02-24T19:15:04Z https://community.nxp.com/t5/Layerscape/Setup-LS1046ARDB-Board-with-1588-PPS-Out/m-p/1008215#M5381 <HTML><HEAD></HEAD><BODY><P><SPAN style="font-size: 10.0pt; background: white;">Check the RCW[EC2] on your board.
