I am trying to run NTPD service on redpitaya. I followed this blog (NTP client for redpitaya) and built the kernel from scratch using this link: http://wiki.redpitaya.com/index.php?title=Red_Pitaya_OS.

But even after fresh build with config files having entry 'BR2_PACKAGE_NTP=y' in config file of build root and 'CONFIG_NTPD=y' & 'CONFIG_FEATURE_NTPD_SERVER =y' in busy box.config, it is still not working. Some other features like wget and * started working but not the required NTPD service. Kindly help me in rectifying this issue.

  • Attach the ps command output and any other debugging that you might have done. – Arpith Jun 12 '15 at 07:17

  • I do not see ntpd running on your system. Did you enable it in services? – Arpith Jun 12 '15 at 08:40
  • I tried but it shows service not found.

  • Busy box doesnt give ntpd by default. Have you cross compiled and ported the ntpd binary for your target? – Arpith Jun 12 '15 at 10:21
  • Yes I did as per instructions in given on link above. – manoj gulati Jun 12 '15 at 11:50
  • Where is the binary on your filesystem? – Arpith Jun 14 '15 at 04:36
  • I have enabled NTP in config file but I am not sure whether including path of NTP binary will help as other packages are included by assigning 'y' in config file. – manoj gulati Jun 15 '15 at 05:34
  • I meant to say if your ntpd binary is in /usr/bin/ntpd then just run "/usr/bin/ntpd" from the shell. If this ends with a successful timesync then you need to add this command in the init or overlay scripts – Arpith Jun 15 '15 at 06:55
