This sample implements some basic tests for the file systems
available. It provides the following functionality:
- perform basic file read/write tests on arbitrary file paths with
selectable I/O buffer size
- perform functions to evaluate FAT disk partition tables
- perform functions to mount FAT disks to the file system tree
A sample session might look like this:
- start this system
- select "p" (part_table_initialize) to read in the partition table of
first harddisk, enter the device name "/dev/hda", when prompted
- select "f" (fsmount) to try to mount the partitions
/dev/hda1../dev/hdc4 to corresponding mount points. Non-existant
partitions will report an error, but will not abort the tests
- select "w" (write file) to create a new file on the mounted disk (or
in the IMFS). Enter the file name (e.g. "/mnt/hda1/test_1M.txt"),
the file size (e.g. 64K or 2M) and the buffer size to use for the
write calls (e.g. 32 or 4K). Then the sample will try to write the
corresponding file and print the time consumed and data rate achived.
- select "r" (read file) to read a file (without displaying the
contents). It has similar parameters as "write file", but does not
query the file size.
- select "s" to call the rtems shell with its various capabilities.
