Post Can't download program to controller
I can download my program to my robot just fine, however I can't do the same for the controller. I searched everywhere, what seems to be the problem here? (attached is the error message image)

Using vex cortex, and the 4.0 robotc application

How are you connecting the controller to the PC? You have to use the USB A-A cable from the PC into the VEXnet port on the controller to update the firmware.

I don't believe you can download any other program to the controller (aside from the firmware). The controller does not run any user programs.

If you're trying to use the programming cable (USB - serial) plugged into the Program port of the controller, that allows the RobotC debugger to download code and control the robot via VEXnet. A very handy thing.
