Introduction

The purpose of this repository is to provide a template to build firmware for DA14531 (Dialog's BLE microcontroller) under CMake with GCC for no code limits. This template integrates SEGGER RTT library for debug printfs through SWD using JLink debug probe (no need for hardware serial).

Author: Mikolaj Stawiski

Requirements

To build the template you'll need:

• CMake >= 3.16 (download from https://cmake.org/download/)
• GCC for ARM (download from ARM's website https://developer.arm.com/). Recommended gcc-arm-none-eabi-10-2020-q4-major.
• Dialog SDK v.6.0.14.1114 (download from Dialog's website https://www.dialog-semiconductor.com/)
• make

Additionally if you want to run the firmware on the target you'll need:

• JLink debug probe
• JLink RTT Viewer (for displaying and logging printfs from the target)
• JLink Ozone debugger >= V3.22a
• Hardware based on DA14531 chip with SWD (e.g. DA14531 Basic USB kit)

Having installed CMake, and downloaded and unzipped GCC for ARM and required Dialog SDK, run build-linux.sh (Ubuntu/WSL/MacOS) or build-windows.bat (Windows) and supply it with paths to GCC and the SDK.

NOTE for Windows

You'll need make to compile the code, for which you might have to install MSYS.

---

Running on target

Upon successful setup and build you'll get firmware files under ./build directory. The firmware will come in few handy formats: binary, hex and elf.

If you want to debug the firmware using Ozone debugger, open DA14531-debug.jdebug with Ozone. The script will load the firmware into target's RAM and name your target's registers for nice debugging experience.

Integration to VSCode

Below is an example of tasks.json for VSCode assuming you're on Linux, installed CMake, downloaded and unzipped GCC for ARM to ~/gcc-arm-none-eabi-10-2020-q4-major/, and downloaded and unzipped Dialog SDK v.6.0.14.1114 to ~/dialog-sdk/:
