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.
