Re: Driver/Connectivity Issue?
I don't know what's causing your problem, but until someone who does comes along, let's see if I can help. First of all, here's a handy chart for deciphering the LED flash codes: http://content.vexrobotics.com/docs/VEX ... 081811.pdf
Now, here's a vague checklist I would run through:
Did you try to download the firmware? Does it work?
How are you trying to download your programs? Directly from the computer to the Cortex through the USB-USB cable, or through the joystick?
What download method are you using? It's under Robot -> Vex Cortex Download Method.
Have you tried a different cable?
See if one of those things is your problem, then we can continue debugging.
A couple versions ago, the "no communication" type errors were terrible, because if nothing else was wrong, it meant sitting there and using the IFI bootloader to reset the firmware, and then praying for the download bar to hit 100% without crashing.
