Hi all,
Im am trying to enable the IEEE1588 PPS and alarm_out output on the EC2 pins.
I have followed the guide https://docs.nxp.com/bundle/GUID-555A0F6D-3FBC-4128-BA29-A220DC5DD74D/page/GUID-15E89810-0E59-4F13-8... and changed the RCW(EC=2), but I cannot measure any PPS-signal on the EC2-pins on my board.
I am using the yocto-sdk with kernel 4.19.
Is there any configuration i need to do in order to route the internal signals to the output pins
Br,
Anders
Solved! Go to Solution.
I have found the problem. I was measuring on the wrong side of R412. I am now able to get a PPS output from the board. Sorry for the inconvenience.
Please provide the FRWY's U-Boot booting log and Linux PTP configuration commands log as textual attachments and explain how the board's Ethernets are connected externally.
