Issue Details

I have created an OPCUA Folder at RT /var/ folder Image following NI Error -356705: OPC UA Toolkit Failed on NI Linux RT to Create Certificate Store. But after copying the modified image with RAD Utility, I've noticed that the OPCUA folder is missing.
 Is this a limitation of RAD Utility?



The RAD Utility is not programmed to copy the /var/ folder the OPCUA certificates are contained in.
The possible workarounds might be:

  • Copy such folder from the cRIO to the host machine, then from the host machine to the cRIO Target of the RAD Image.
  • Do the same programmatically, for example, use the WebDAV APIs for the file transfer.
