1 Overview
The aBLE EVK mounts an aBLE chip (A31R118), to evaluate its performance. The aBLE EVK can be
used as a prototype development board too.
This development kit board has the following key features:
BLE SOC
Buttons and LEDs for user interface
I/O interface for Arduino Shield Compatible plug-in module modules
CMSIS-DAP compatible debug port with
—Virtual COM Port interface via UART
—Drag and Drop Mass Storage Device(MSD) programming
Requirements for hardware and software before enabling the aBLE EVK are listed below:
Hardware
—aBLE Evaluation Board Kit (EVK)
—Arduino plug-in modules (optional)
Software
—aBLE SDK
—Toolchain, any of
▪Keil uVision (Preferred)
▪GNU GCC
▪IAR Embedded Workbench
Document
—Datasheet for aBLE
—aBLE EVK User Guide (this document)
—aBLE EVK hardware files
—aBLE Application Notes

2 Getting started
aBLE SDK contains many examples for the MCU peripherals and the BLE applications. In following
sections, general processes of building, loading, and running a BLE application on the EVK are
described. Any toolchains can be used to build examples for each process, and Keil uVision is used in
this document.
For A31R118 EVK, refer to following sections:
Section 2.1 Building firmware
Section 2.2 Downloading the firmware
Section 2.3 running application from RAM space

2.1 Building firmware
The general process of building firmware is shown below:
1. Download and install Keil uVision (Lite version is sufficient for all examples).
2. Select an example to build in the example folder.
3. Double click on the example project file (*.uvprojx).
4. Modify chip specific settings (preprocessor and scatter loading file).
5. Click on a button “Build” or “Rebuild”.

2.1.1 C Pre-processor
The preprocessor defines a macro containing “A31R118”. It must be set correctly according to the chip
used as shown in Figure 1 (example of A31R118).
For A31R118, use “A31R118”
Figure 1. C Pre-processor

2.1.2 Scatter loading
The scatter loading file for BLE applications must be set properly as shown in Figure 2 (example of
A31R118).
●For A31R118, use target_a31r118.sct
Figure 2. Scatter Loading
To run the application of RAM, use target_a311x_ram.sct (refer to section 2.3).

2.2 Downloading firmware
Once the build of example application is complete successfully, the firmware can be downloaded onto
the EVK by using one of the two different methods:
Method 1. Keil’s download feature
Method 2. Drag and drop.
2.2.1 Downloading with Keil
1. Select the CMSIS-DAP debugger from the debugger selection menu.
Figure 3. Debugger Set

2. Make sure that the debugger settings and connections are proper by checking the SW device
ID.
Figure 4. Read Device ID
3. Copy the flash download algorithm files provided in the SDK to the Keil’s flash directory.
—aBLE flash algorithm files: “<aBLE SDK Root>\flash\*.flm”
—Keil’s flash directory: “<Keil install root>\ARM\Flash\”
▪Typically, the flash download algorithm files are located at “C:\Keil_v5\ARM\Flash”.

—[Project] menu
—[Options for Target A31R11X]
—[Debug] tab
—[Settings] button
—[Flash Download]
—[Add] button
—Select the proper file according to the chip used.
