CooCox Colink is a small ARM Cortex M3 JTAG hardware debugging probe.
I had thought that it only supports Keil RealView MDK, but later I learned that he also supported IAR Embedded
Workbench. I'm sorry that I tell you about this so late.
It integrates seamlessly into IAR Embedded Workbench, Keil RealView MDK, CooCox CoDebugger and CooCox CoFlash.
