we have enabled PPS output from ptp driver by changing device tree to reassign SODIMM 222 to MX8MM_IOMUXC_GPIO1_IO09_ENET1_1588_EVENT0_OUT. We have also changed the driver to toggle the EVENT0_OUT pin (as opposed to a short pulse) so we can see the result more easily on our oscilloscope. The PPS out is enabled by
echo 1 > /sys/class/ptp/ptp0/pps_enable
When linuxptp (v3.1.1) has slaved to a master.
However, the pin toggles every 2.16s, not once per second. Has anyone got pps output from the fec_ptp driver working on the Verdin with linuxptp?
