Cortex not working

My cortex is not sending power to my vexnet and it won’t connect to my controller and robotc won’t recognise it. I’ve tried to reset the cortex but that doesn’t work. Here is a picture of the cortex when I turn it on.

Please reply. I need help!!!

I’d recommend you check the USB port on you cortex, they are reasonably easy to break so might be the cause of your problem.




Good USB

The usb port on the outside is not the problem. We think there is a problem with the inside.

Try following this troubleshooting guide for the cortex

If its more complex than that I can’t really help, sorry.

Download VEX’s firmware updater utility. Update the master firmware on the Cortex and download the default user code, then try downloading the ROBOTC code.
