Introduction

sdk-bsp-psoc_e84-edgi-talk is the RT-Thread Board Support Package (BSP) for the PSoC™ E84 Edgi-Talk development board. It can also be used as a software SDK for user development, enabling developers to build their own applications more easily and efficiently.

The Edgi-Talk board is based on the PSoC™ E84 MCU and provides a flexible and comprehensive development platform. It integrates a variety of peripheral interfaces and sample modules, helping developers quickly implement applications involving multi-sensor integration, display, and communication.

Usage

sdk-bsp-psoc_e84-edgi-talk supports development using RT-Thread Studio.

RT-Thread Studio Development Steps

1. Open RT-Thread Studio and install the Edgi-Talk BSP (latest version recommended).
2. Create a new Edgi-Talk project: File -> New -> RT-Thread Project -> Based on Board. Example and template projects are available for selection.
3. Build and download the project: Compilation, download, and debugging can be done directly inside RT-Thread Studio.

Notes

• To modify the graphical configuration of the project, use the following tool to open the configuration file:

  tools/device-configurator/device-configurator.exe
  libs/TARGET_APP_KIT_PSE84_EVAL_EPC2/config/design.modus
  

• After modification, save the configuration and regenerate the code.

Boot Sequence

The system boot sequence is as follows:

+------------------+
|   Secure M33     |
|   (Secure Core)  |
+------------------+
          |
          v
+------------------+
|       M33        |
| (Non-secure Core)|
+------------------+
          |
          v
+-------------------+
|       M55         |
| (Application Core)|
+-------------------+

⚠️ Please strictly follow the above sequence when flashing firmware; otherwise, the system may fail to run properly.

---

• If example projects cannot run correctly, compile and flash the Edgi-Talk_M33_S_Template project first to ensure core initialization and startup flow are functioning before running other demos.

• To enable the M55 core, configure it inside the M33 project:

  RT-Thread Settings --> Hardware --> select SOC Multi Core Mode --> Enable CM55 Core
