The kit firmware is the application that enables the kit to do debugging, current measurements, flashing, virtual COM port, among other things.


Key Features

USB Mass Storage Device (USB MSC)

  • Program binary images to target by simply copying them to the flash drive in your operating system.
  • MSC programming supports flat binary files, Motorola S-record files and Intel Hex format files.

Virtual COM port (USB CDC)

  • A virtual serial port which can be used for communications between a computer and the target application.
  • Available whenever the J-Link USB cable is connected to a computer.
  • Fixed configuration; 115 200 bps, 8 data bits, no parity bit, 1 stop bit.

Advanced Energy Monitoring (AEM)

  • Monitor the current and energy use of the target application in real time.
  • Correlate energy consumption to code segments using Energy Profiler in Simplicity Studio.

Debug Multiplexer

  • A multiplexer on the board enables debugging of an external target (such as a custom board) using a standard cable.
  • Controlled using the Kit Manager in Simplicity Studio.


Supported Kits

ARM mbed is at this time supported by the STKs listed below.

SEGGER J-Link Version

If you are using the SEGGER J-Link driver and/or tools, please ensure you are using the latest version to avoid problems. This is taken care of in Simplicity Studio, but if you are using other tools please ensure that you are using a recent release from segger.com
