    is your config file static (Which is prepared offline on Host) or dynamically created during run time?

    If it is static file and you want to save it in flash: first make sure the following:


    • Initialize the FLASH on system startup.
    • Make sure the proper Read/Write permissions are provided.
    • Expose some section of the Flash which is reserved for the File system.
    • The section reserved for the File system should be accessable by some tool on Host PC and then you can copy/move the config file to File system section using the tool on Host PC.
      If the Config file is generated dynamically during run time:


    • Initialize the FLASH on system startup. Reserve Section of Flash for FIle system and provide proper Access permission.
    • During run time when you want to create/save config file, then use File System API and save the file in File System section of Flash.
