stm32f103 WQ25xx初始化失败

软件：tag中的3.1.3版本，bsp是stm32f10x-HAL
硬件：WQ25Q128，连在spi1上面
现象：读取不到flash信息，示波器量了有CLK和写数据，没有读数据
日志信息如下：
```DEV_W25QXX:GPIO Init Pass in rt_dev_w25qxx_cs_init.
name = hw_spi_1
object = hw_spi_1 
DEV_W25QXX:Bus Attach Pass in rt_dev_w25qxx_attachcs.
DEV_W25QXX:device w25qxx attach cs success.
flash_device_name = flash0,spi_device_name = spi_dev
name = spi_dev
object = spi_dev
rt_spi_device = spi_dev
rt_spi_device = 4

```

再次确认：用我们其他项目的使用标准库的代码是可以读到flash信息的。

请问有谁用这个bsp读取访问过flash吗，求教
