roboRIO 2.0 - Broken CAN

[Julie1919]

The CAN is not detected by the CPU of the roboRIO. Probably a chip on the PCB is broken.

Hi Julie1919,

This is Jessica from NI Technical Support. Thank you for posting to the forums.

Is CAN not being detected at all?

• Is the roboRIO firmware updated?
• Have you checked the wiring and tested different cables?
• Do you have another roboRIO that you can use to reproduce the error?

[Julie1919]

No the CAN can't be detected at all.. 

Yes the firmware is updated (2025.3)

Yes we tested different cables and no detection

It's really an electric problem with this specific roboRIO. 

Thanks
