Issue Details

I can't connect to my cRIO-908x controller. If I read the console output, I see the following error:
Transferring control to user program
Datalight Reliance v2.10.1053
Copyright (c) 2003-2006 Datalight Inc.
Reliance v2.10 Build 1053: Assertion failure in module rlinode.c line 1138 (DCL=351)

How can I troubleshoot this issue?


You can follow the steps in this KnowledgeBase article to format the controller. Although those steps are meant to be done on PXI targets, it remains applicable to cRIOs as well.
If those steps will not help, your device is damaged. In this case, contact National Instruments Technical Support.
