Hello, I have an update. I obtained the HEAD for linuxptp yesterday and re-ran my setup. Unfortunately, phc2sys failed again with a Connection timed out:
phc2sys[470789.265]: CLOCK_REALTIME phc offset -63 s2 freq -9645 delay 0 phc2sys[470790.265]: CLOCK_REALTIME phc offset -797 s2 freq -10398 delay 0 phc2sys[470791.266]: CLOCK_REALTIME phc offset 524 s2 freq -9316 delay 0 phc2sys[470792.266]: CLOCK_REALTIME phc offset 598 s2 freq -9085 delay 0 phc2sys[470793.266]: CLOCK_REALTIME phc offset -247 s2 freq -9750 delay 0 phc2sys[470794.267]: CLOCK_REALTIME phc offset -22 s2 freq -9599 delay 0 phc2sys[470795.267]: ioctl PTP_SYS_OFFSET_PRECISE: Connection timed out Is there something I can do to troubleshoot this? Our application needs to run for days. My solution is to modify the phc2sys's sysoff_precise to just use the last pctns and ts result when an ioctl error happens. when this connection timed out happen, ptp4l is still running. regards,bernardo On Wed, May 17, 2023 at 10:46 AM Bernie Gmail <bela...@gmail.com> wrote: > > Thank you!
