|
* 程序清单：这是一个 dfs 虚拟文件系统挂载文件系统使用例程
|
|||
|
|
* 例程导出了 mnt_init 命令到应用初始化中
|
|||
|
|
* 程序功能：挂载 elm 文件系统到片上flash filesystem 分区中
|
|||
|
|
* 使用前参考文章 https://blog.csdn.net/h451884098/article/details/118544347 和 https://blog.csdn.net/u013213069/article/details/117384971 开启以下配置：
|
|||
|
|
* 1、修改 menuconfig 打开RT_USING_DFS 和 elm-chan 文件系统并修改扇区 sector 大小为 4096
|
|||
|
|
* 2、修改 components/dfs/dfs_v1/include/dfs.h 和 components/dfs/dfs_v2/include/dfs.h 中 SECTOR_SIZE 改为 4096
|
|||
|
|
* 3、修改芯片外设配置打开 BSP_USING_ON_CHIP_FLASH
|
|||
|
|
* 4、修改 menuconfig 打开 RT_USING_FAL 配置
