Debugging Cortex with ARM Keil Development Tools
The sharpest tools in the box!
When developers first start to use an ARM Cortex-M based microcontroller, they often assume that debug support is provided through a JTAG interface. In fact, while legacy JTAG support is provided the Cortex-M processor family uses ARM’s proprietary debug architecture called CoreSight. JTAG works by taking control of the processor and injecting instructions into the CPU.
