This page describes step by step how to update de debugger firmware. Note that the firmware version is associated with a specific version of CooCox. When you update CoIDE to a newer version, the debugger firmware and the USB driver needs an update too.

When you are using CoIDE version 1.3.x; It has been tested that the Simplecortex isnĀ“t working properly with some kind of computer. Try the firmware 0.3 V2 to solve the problem.
