Cortex Not Updating

Our club has some cortices from three years ago, and recently the robotics club underwent a rebirth of sorts. We’ve been trying to update the cortices, but whenever we try to do so, all that’s displayed is “cortex could not be found” or something like that (will check later). We’ve been using the old programming cables to hook up the cortices to the computer.

RobotC software version: 3.61 and 4.0

Cortex firmware: unknown (they’re from three years ago)

There was one forum post from a while back that had the same problems as ours, but it was left unanswered. I’ll look for the link to the thread later, can’t find it now.

Thanks for all your help!

Try using the VEXnet firmware update utility (link) and a USB A-A cable to do the updates.
