rt-thread(5.0版本)之sfud组件的使用问题记录(w25q128存储模块)

本文主要是介绍rt-thread(5.0版本)之sfud组件的使用问题记录(w25q128存储模块)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前言

记录一下5.0版本时使用官方推荐的函数与底层驱动存在的不兼容问题

在这里插入图片描述

使用旧的api函数

硬件驱动(使用的SPI1)

#include "board.h"
#ifdef RT_USING_SPI
/**
* @brief SPI MSP Initialization
* This function configures the hardware resources used in this example
* @param hspi: SPI handle pointer
* @retval None
*/
void HAL_SPI_MspInit(SPI_HandleTypeDef* hspi)
{GPIO_InitTypeDef GPIO_InitStruct = {0};if(hspi->Instance==SPI1){
#ifdef BSP_USING_SPI1/* USER CODE BEGIN SPI1_MspInit 0 *//* USER CODE END SPI1_MspInit 0 *//* Peripheral clock enable */__HAL_RCC_SPI1_CLK_ENABLE();__HAL_RCC_GPIOB_CLK_ENABLE();/**SPI1 GPIO ConfigurationPB3     ------> SPI1_SCKPB4     ------> SPI1_MISOPB5     ------> SPI1_MOSI*/GPIO_InitStruct.Pin = GPIO_PIN_3|GPIO_PIN_4|GPIO_PIN_5;GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;GPIO_InitStruct.Pull = GPIO_NOPULL;GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);/* USER CODE BEGIN SPI1_MspInit 1 *//* USER CODE END SPI1_MspInit 1 */
#endif}}#endif

w25q128驱动组件

//
// Created by shchl on 2024/3/20.
//#include "board_w25q128.h"
#include "board.h"
#include "drv_spi.h"
#include "spi_flash_sfud.h"static int rt_hw_spi_flash_init(void) {if (RT_EOK != rt_hw_spi_device_attach("spi1", "spi10", GPIOB, GPIO_PIN_14)) {LOG_E("Failed to attach the spi device.");return -RT_ERROR;}if (RT_NULL == rt_sfud_flash_probe("W25Q128BV", "spi10")) {LOG_E("Failed to probe the W25Q128.");return -RT_ERROR;};return RT_EOK;
}/* 导出到自动初始化 */
INIT_COMPONENT_EXPORT(rt_hw_spi_flash_init);

测试结果(ok)

使用5.0版本之后(官方推荐函数)

硬件驱动(同上)

}/* 导出到自动初始化 */
INIT_COMPONENT_EXPORT(rt_hw_spi_flash_init);

运行结果(出现错误)
