How to run phc2sys command line option? #3

Open sinlam opened 2 years ago

Hi, I would like to find out how to synchronize the clock from the Wifi adapter to the local system clock using phc2sys (compiled from your ptp dir)? Any information is appreciated, thank you!

Use linuxptp. We forked one in the repo: ptp.

Thank you for the info. I have compiled the linuxptp that you forked. Can you share exact command to synchronize system clock from the Wifi TSF counter? I used phc2sys from the forked 'ptp' as below:

sudo phc2sys -s wlan0 -c CLOCK_REALTIME --step_threshold=1 --transportSpecific=1 -w -m

But it is not successful. Thanks for any info!

Can you provide the error log? Turn off NTP.

Hi, Thanks for your suggestion. Currently I am on vacation, I will try it again early April when I go back to office and provide you the error log. Thanks!
