    Thanks for your replay.
    I found the problem finally.
    First, i wrote "w" in uppercase.so the hFile is invalid.
    Second,SPI Flash base on EFS.
    RL-FlashFS » Embedded File System » Limitations contains the information:
    Directories or folders are not supported.
    File names are preprocessed to remove the path information for non-FAT file systems.
    So i can't create any subdirectory on a SPI file system.
