就是挂载SPI FLASH的时候失败，代码：
int rt_hw_spi_flash_init(void){ int ret; __HAL_RCC_GPIOA_CLK_ENABLE(); ret = rt_hw_spi_device_attach("spi1", "spi10", GPIOA, GPIO_PIN_4); if (ret != RT_EOK) { rt_kprintf("rt_hw_spi_device_attach failed! \n"); return ret; } else { rt_kprintf("rt_hw_spi_device_attach succ! \n"); } if (RT_NULL == rt_sfud_flash_probe("W25Q256", "spi10")) { rt_kprintf("rt_sfud_flash_probe failed! \n"); return -RT_ERROR; } return RT_EOK;}INIT_COMPONENT_EXPORT(rt_hw_spi_flash_init);
打印的log：

在哪可以查看SPI FLASH初始化
芯片的数据读取的全部为0。所以是失败的。
可以参考Pandora STM32L475 的 W25Q128的驱动。
