Usage of Memory File System:
|
|
1. Read/write file system on RAM in a MicroBlaze based platform
|
|
a. Compile mfs_filesys.c along with your application code. mfs_filesys.c include xilmfs.h
|
|
b. Invoke mfs_init(NUM_BYTES, BASE_ADDRESS, MFSINIT_NEW) within your application
|
|
before calling any MFS functions.
|
|
- NUM_BYTES is the number of bytes allocated to the MFS
|
|
- BASE_ADDRESS is the starting address of the memory block allocated to MFS
|
|
- this can be obtained by calling a memory allocator such as malloc()
|
|
or by directly reserving this in the system MHS file
|
|
- MFSINIT_NEW is a constant defined in xilmfs.h
|
|
- NUM_BYTES and BASE_ADDRESS can optionally be generated through libgen
|
|
- in which case they are placed in the mfs_config.h file and
|
|
- the mfs_filesys functions are part of the standard libraries
|
|
|
|
|
|
2. Read-only file system on SRAM/Flash or pre-initialized file read/write system on SRAM
|
|
- See the readme.txt file in the utils directory for more info
