| |
Hi,
I'm trying to use PPS_ECHOASSERT with the GPIO pins on a Raspberry Pi. /sys/class/pps/pps0/echo reports 1, however looking at pps-gpio.c, no echo-callback is registered. Am I missing something or should either sysfs report 0 or pps echo be implemented in the client?
From a quick glance at the other clients, the same might be true for pps-ktimer and pps_parport. They both report PPS_ECHO* in info.mode but never define info.echo.
Cheers, Lukas
