After the partition in the external FLASH mounts the FAT file system, a delete folder can be created, but mkfs operations and read/write file operations cannot be performed

[SanKin42]

芯片：STM32F407ZGT6 工具链：arm-none-eabi-gcc RT-Thread版本：RT-Thread v5.0.1

如题，基本条件和官方例程中一致，W25Q128被切分成了几个区，我目标是将filesystem区挂载为文件为文件系统根目录，挂载成功后能创建删除文件夹，但是无法进行mkfs操作和读写文件操作。

目前可以确认flash无硬件问题，我已测试从flash中读写数据和擦除flash操作。

控制台记录如下：

config如下：

Coder如下：
