Hello, I am currently having trouble downloading a program onto the cortex of my VED EDR robot, it allows me to download a sample program, but not one I create, I was instructed that I need to flash the firmware, I’m not entirely sure what that means, any help?

This could have stayed in the other thread.

Go here:

Download the utilities, use a USB A-A cable to plug in each device (joystick, Cortex, VEXnet key) one at a time and let the firmware utility check them.

Our firmware is up to date on our robot, that was the first thing we did was download the new firmware, but it still does not allow us to put our own program onto the cortex.
