Routing Pulse Out to 1588 Test Header Pin LS1046ARDB

Hello,

 

After installing the Layerscape Software Development Kit, I've been using this guide to enable PPS leveraging my PTP hardware clock. Now I want to know if it is possible to route this PPS signal to hardware pin on the board (maybe the 1588 test header pins) so that I could hook up a scope and measure the delay. Does anyone have a guide on how to do this?

 

I've read around and notice that there are documentation about leveraging the reset configuration words (notably RCW[EC2]) to enable the use of this 1588 test header but I have not found any documentation regarding how to do this.

 

Any help would be appreciated!
