Syntax
memtest ( [-sa <start_address>] [-ea <end_address>] [-l <length>]
[-bs <block_size>] [-i <address_inc>] [-p <pass_count>]
[-d <data_pattern>] [-rs <random_seed>] [-ba <block_address>]
[-t <test_mask>] [-se <soft_error_threshold>]
[-g <group_name>] [-rb] [-f] [-m] [-z] [-h] [-mb] )
Options
-sa
Start address. Default is first free space in memzone.
-ea
End address. Default is start address plus length size.
-l
Length of section to test in bytes, default is the zone size with the
-rb option and the block_size for all other tests. -l has precedence
over -ea.
-bs
Block (packet) size in bytes in hex, default 8192 bytes. This is used
only for the random block test. For all other tests the block size
equals the length.
-i
Specifies the address increment value in longwords. This value is
used to increment the address through the memory to be tested.
The default is 1 (longword). This is only implemented for the
graycode test. An address increment of 2 tests every other
longword. This option is useful for multiple CPUs testing the same
physical memory.
-p
Passcount If 0 then run indefinitely or until Ctrl/C is issued.
Default = 1
-t
Test mask. Default = run all tests in selected group.
-g
Group name
-se
Soft error threshold
-f
Fast. If -f is included in the command line, the data compare is
omitted. Detects only ECC/EDC errors.
