1.13 MPFS File System Using NVM Media

Description

File System Operations on NVM

The application contains an MPFS disk image in the internal Flash memory. The disk image contains two files named:
- FILE.txt, Size = 11 bytes. The content of the file is: Hello World
- TEST.txt, Size = 10 bytes. The content of the file is: 1234567890
The application performs following file system related operations:
- SYS_FS_FileRead
- SYS_FS_FileStat
- SYS_FS_FileSize
- SYS_FS_FileSeek
- SYS_FS_FileEOF
The contents of both the files are read and compared with the expected strings as mentioned above. If the string compare is successful, an LED indication is provided.

File System Layer Uses
