Debug Utils RAM Dump#

1. Purpose / Scope#

This section provides examples to easily configure and execute debug applications of RS9116 module.

The RAM dump application is use to read the RAM content of RS9116W module for a given address.

2. Prerequisites / Setup Requirements#

Before running the application, the user will need the following things to setup.

2.1 Hardware Requirements#

• Windows PC with Host interface(UART/ SPI).

• Silicon Labs RS9116 Wi-Fi Evaluation Kit

• Host MCU Eval Kit. This example has been tested with:

  • Silicon Labs WSTK + EFR32MG21

  • STM32F411 Nucleo

2.2 Software Requirements#

• WiSeConnect SDK

• Embedded Development Environment

  • For STM32, use licensed Keil IDE

  • For Silicon Labs EFx32, use the latest version of Simplicity Studio

3. Application Build Environment#

3.1 Platform#

The Application can be built and executed on below Host platforms

• STM32F411 Nucleo

• WSTK + EFR32MG21

3.2 Host Interface#

• By default, the application is configured to use the SPI bus for interfacing between Host platforms and the RS9116W EVK.

• The SAPI driver provides APIs to enable other host interfaces if SPI is not suitable for your needs.

3.3 Project Configuration#

The Application is provided with the project folder containing Keil and Simplicity Studio project files.

• Keil Project

  • The Keil project is used to evaluate the application on STM32.

  • Project path: <SDK>/examples/snippets/debug_utils/ram_dump/projects/ram_dump-nucleo-f411re.uvprojx

• Simplicity Studio

  • The Simplicity Studio project is used to evaluate the application on EFR32MG21.

  • Project path:

    • If the Radio Board is BRD4180A or BRD4181A, then access the path <SDK>/examples/snippets/debug_utils/ram_dump/projects/ram_dump-brd4180a-mg21.slsproj

    • If the Radio Board is BRD4180B or BRD4181B, then access the path <SDK>/examples/snippets/debug_utils/ram_dump/projects/ram_dump-brd4180b-mg21.slsproj

      • User can find the Radio Board version as given below

3.4 Bare Metal Support#

This application supports only bare metal environment. By default, the application project files (Keil and Simplicity Studio) are provided with bare metal configuration.

4. Application Configuration Parameters#

The application can be configured to suit your requirements and development environment. Read through the following sections and make any changes needed.

4.1 Open rsi_ram_dump.c file and update/modify following macros,

Path : /examples/snippets/debug_utils/ram_dump

This define should be ENABLE only in case of linux platform with USB interface, by default, it is DISABLE

#define LINUX_PLATFORM         DISABLE

Address in Silicon Labs module

#define READ_ADDRESS           0x0

5. Testing the Application#

User has to follow the below steps for the successful execution of the application.

5.1 Loading the RS9116W Firmware#

Refer Getting started with PC to load the firmware into RS9116W EVK. The firmware binary is located in <SDK>/firmware/

5.2 Building the Application on the Host Platform#

5.2.1 Using STM32#

Refer STM32 Getting Started

• Open the project <SDK>/examples/snippets/debug_utils/ram_dump/projects/ram_dump-nucleo-f411re.uvprojx in Keil IDE.

• Build and Debug the project

• Check for the RESET pin:

  • If RESET pin is connected from STM32 to RS9116W EVK, then user need not press the RESET button on RS9116W EVK before free run.

  • If RESET pin is not connected from STM32 to RS9116W EVK, then user need to press the RESET button on RS9116W EVK before free run.

• Free run the project

• Then continue the common steps from Section 5.3

5.2.2 Using EFX32#

Refer EFx32 Getting Started

• Import the project from <SDK>/examples/snippets/debug_utils/ram_dump/projects

• Select the appropriate .slsproj as per Radio Board type mentioned in Section 3.3

• Compile and flash the project in to Host MCU

• Debug the project

• Check for the RESET pin:

  • If RESET pin is connected from STM32 to RS9116W EVK, then user need not press the RESET button on RS9116W EVK before free run

  • If RESET pin is not connected from STM32 to RS9116W EVK, then user need to press the RESET button on RS9116W EVK before free run

• Free run the project

• Then continue the common steps from Section 5.3

5.3 Common Steps#

1. Build and launch the application.

2. After the program gets executed RAM content is saved in ram_content buffer. In case of USB interface RAM content is saved in file dump.txt.

6. Compressed Debug Logging#

To enable the compressed debug logging feature please refer to Logging User Guide
