Issue Details

My roboRIO is powered on and my Power LED is solid green. However, the RSL LED is not on. 


The RSL LED may be off if there is not software or an FPGA bitfile loaded onto the roboRIO. Use the FRC Imaging Tool to format the roboRIO which will install software on the roboRIO.

Additional Information

Other LEDs on the device may give a better idea of the state of the roboRIO. For instance, if the Status LED is blinking twice, this may indicate that the RSL light is not on because there is an error in the image on the device. Consult the NI roboRIO manual for more information about LED statuses and what they mean.
