User Guide
Besides the typical JTAG debugging, I-jet is capable of providing power to the target
board and measuring it with sufficient accuracy to provide a power profile during
program execution in real time. This feature is referred to as power debugging.

For debugging Cortex-M devices, I-jet supports the SWO (Serial Wire Output) feature,
which can be used for tracing the program execution and sending variables at predefined
points in your code. I-jet streams the program counter, variables, and power
measurement data to the host PC to provide a much better view into program execution
in real time.
I-jet needs to be controlled by the IAR C-SPY® Debugger which comes with the IAR
Embedded Workbench® IDE.
