As an alternative to the Net4501, the AM335x in the Beaglebone has timers that accept an external clock up to 25 MHz (TCLKIN) and can timestamp events on an input pin (TIMER4-TIMER7). Both sets of pins are available on the headers after an appropriate pinmux configuration.
I'm finishing the clocksource driver for Linux, I'm testing it using the 10 MHz and PPS outputs of a LEA-6T. ntpd loopstats show +/- 0.1 us offsets, frequency is a flat 0.000 PPM as expected. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
