1Introduction
This document introduces software environment and development recommendations for the ABOV 32-
bit Cortex-Mx Starter Kit. In this document, an easy method how to develop the ABOV 32-bit Cortex-
M0x MCUs on a Starter Kit board.
The Starter Kit board contains a CMSIS-DAP debugger which is called “A-Link”. This is the interface
firmware for a debug unit that connects the debug port to USB. The debug unit connects via JTAG or
SW to the target device. Using this CMSIS-DAP debugger (A-Link), you can eliminate the needs for
additional devices when programming and debug the MCU.
In this document, you can learn a method how to operate the A31G324RLN Shield board, as an
example, step by step.
