4.2 Software project
To open the software project, edit, compile and load the Software into K81 target, 2 IDEs
can be used: IAR and KDS.
4.2.1 Debug Probe – J-Link
The program download into the K81 requires a J-Link probe to be connected between
the computer and the K81 target.
J-Link probe is used for this purpose and can as well be used to debug the program
running in the K81 target. This connection requires at a minimum a J-Link Base probe,
and a 19-pin Cortex-M Adapter, to connect the probe to the K81 module:

Probe drivers should be automatically installed during the installation of the IDE.
The probe and the adapter are not part of the kit. They have to be purchased
separately.
The first time the probe is used, its driver has to be installed. Driver and instructions can
be found under JLINK website: choose the “
J-Link Software and Documentation
Pack” download:

4.2.2 Debug information (printf)
Some debug information can be received through UART, using a Serial board extension.
