cRIO Time-Synchronization NTP when cRIO is offline

Solved!

All

 

I am trying to synchronize my cRIO to a NTP server that is hosted on an accessible intranet but no access to internet. I was looking at 

https://forums.ni.com/t5/Example-Code/Installing-and-Configuring-NTP-on-NI-Linux-Real-Time-Devices/t...

 

I was going to download the opkg package offline from https://downloads.openwrt.org/releases/, and transfer via USB to the cRIO and install.

 

It looks like opkg is target dependent. It looks like cRIO 9045 is armv7, but how do I match that with the compatible targets for opkg? Thoughts?

There are feeds which have a lot of standard packages compiled for Linux RT systems at http://download.ni.com/ni-linux-rt/feeds/ .

 

Also, I believe the 9045 is x64 and not arm.

I ended up following these 2 links and it solved my issue 🙂

 

https://www.slideshare.net/BryanHeslop1/configuring-compactrio-to-synchronize-clocks-with-ntp-server...

Above link specifically addresses synchronizing cRIO to NTP when there is no internet available

 

https://www.cyberciti.biz/faq/linux-unix-bsd-is-ntp-client-working/

tells how to verify

 

(this is good for people who are not linux savvy)
