Solution
This error is usually related to connectivity issues, either caused by the network/firewalls or the unit itself struggling when communicating. There can be many root causes of this issue, these are some of the troubleshooting steps you can follow to solve it:
- Make sure no local or network firewalls are blocking communication. Disable any Windows firewalls and anti-virus temporarily, if possible, isolate the host PC and the cRIO in a straight ethernet communication with no corporate network access to test out connection.
- Make sure the cRIO can be pinged from the PC and it shows up correctly in NI MAX with no errors or warnings.
- Double check the board's LEDs are not pointing to an internal software corruption.
- Reset the cRIO using the reset button on the cRIO.
- Try manually installing the NI Linux RT Image and feeds from NI MAX: Remote Devices >> cRIO Target>> Software >> Right click >> Add/Remove Software.
- If other targets do work normally using the same PC and network, it could the specific unit has some OS level corruption. Try restoring factory settings: Restore NI Linux RT Target to Factory Default Configuration - NI
- Try using a different PC to perform the imaging.
