Integrating IF573 on NUCLEO-H745ZI-Q via Ezurio STM32 Nucleo Adapter Card

Introduction

The STM32 Nucleo Adapter Card is designed for effortless integration with the Nucleo-144 form factor board. Featuring 144 pin headers, it connects seamlessly to the STM32 Nucleo board without the need for any hardware modifications. Furthermore, it includes a MikroBUS interface that facilitates peripheral expansion.

This guide outlines the process for configuring the setup on STM32CubeIDE and executing Wi-Fi functionality on the NUCLEO-H745ZI-Q using FreeRTOS. The tutorial specifically focuses on the example related to IF573.

Hardware Setup

In the images provided, you can observe the NUCLEO-H745ZI-Q with a Nucleo-144 adapter on the left, alongside the STM32 Nucleo Adapter Card with the IF573 positioned on top of it on the right.

453-00119 (IF573, M2, SDIO) is plugged into M.2 slot.

Hardware Setup

Note: Ensure that the power source is configured to +5V, as indicated in red above.

Prerequisites

The following software needs to be installed:

STM32CubeMX: For generating code by integrating firmware and packages.
STM32CubeIDE: IDE for compiling, flashing, and debugging via ST-Link.
STM32CubeProgrammer: For flashing binary files onto STM32 boards.

Updating Software

STM32CubeMX: Installing Updates

Launch STM32CubeMX:

Navigate to Help > Check for Updates.
Refresh the list, select the new version, and click Install.

Install STM32 Connectivity Expansion Pack v1.7.1

Open STM32CubeMX and select Install/Remove under Manage Software Installation.
Click the Infineon tab, refresh, select version 1.7.1, and click Install.
Close STM32CubeMX.

Configuring application with STM32CubeMX

Open project in STM32CubeMX

Copy wifi_bt_tester from the repository:

 C:\Users\%USERNAME%\STM32Cube\Repository\Packs\Infineon\AIROC-Wi-Fi-Bluetooth-STM32\1.7.0\Projects\NUCLEO-H745ZI-Q\Applications

to your personal directory:

C:\Users\%USERNAME%\STM32Cube\Examples

Rename <application>\STM32CubeIDE to <application>\STM32CubeIDE.org.
Double-click wifi_bt_tester.ioc to open in STM32CubeMX.
Select Migrate if prompted.
Under Pinout & Configuration, select Software Packs > Select Components.

Configuration

Disable Bluetooth components (btstack, btstack-integration).
Choose CYW55572 as the device and SONA-IF573 as the module.
Come back to Pinout page. Under FREERTOS_M7 > Advanced settings, enable USE_NEWLIB_REENTRANT.

Generate Code

Click Generate Code and open the project.

Restore Original Linker Script

Once project is open in STM32CubeIDE, copy linker script from:

...\STM32CubeIDE.org\CM7\STM32XXXX_FLASH.ld

to:

...\STM32CubeIDE\CM7\STM32XXXX_FLASH.ld

Building Application in STM32CubeIDE

Modify source codes

Delete bt_cfg.c and bt_utility from:

wifi_bt_tester_CM7 > Middlewares > Connectivity > Wireless > MfgTools > command-console

Delete bt files

Modify console_task.c located at Application > User > Core:

Insert (Private macro section):

#define SDMMC1_D0 PC8
#define SDMMC1_D1 PC9
#define SDMMC1_D2 PC10
#define SDMMC1_D3 PC11

Comment out:

//bt_utility_init();

Add GPIO initialization code before the stm32_cypal_wifi_sdio_init() function:

cyhal_gpio_init(SDMMC1_D0, CYHAL_GPIO_DIR_OUTPUT,CYHAL_GPIO_DRIVE_PULLUP, false);
cyhal_gpio_init(SDMMC1_D1, CYHAL_GPIO_DIR_OUTPUT,CYHAL_GPIO_DRIVE_PULLUP, false);
cyhal_gpio_init(SDMMC1_D2, CYHAL_GPIO_DIR_OUTPUT,CYHAL_GPIO_DRIVE_PULLUP, false);
cyhal_gpio_init(SDMMC1_D3, CYHAL_GPIO_DIR_OUTPUT,CYHAL_GPIO_DRIVE_PULLUP, false);
cyhal_system_delay_ms(10);
cyhal_gpio_write(SDMMC1_D0, true);
cyhal_gpio_write(SDMMC1_D1, true);
cyhal_gpio_write(SDMMC1_D2, true);
cyhal_gpio_write(SDMMC1_D3, true);
cyhal_system_delay_ms(10);
cyhal_gpio_free(SDMMC1_D0);
cyhal_gpio_free(SDMMC1_D1);
cyhal_gpio_free(SDMMC1_D2);
cyhal_gpio_free(SDMMC1_D3);

Add Build Macro

Right-click wifi_bt_tester_CM7, select Properties.
In C/C++ Build > Settings > MCU Settings, enable Use float.
Under C/C++ Build > MCU GCC Compiler > Preprocessor, add macro BLHS_SUPPORT. Then apply and close.
Right-click on wifi_bt_tester_CM7 and select Convert to C.
