3.1.103 testRamRandom

Name

testRamRandom—assures addressability of memory, using a memory test block. Addressing
errors are sought by writing a random pattern and its complement to each location. The test
proceeds as follows: (1) A random pattern is written throughout the test block. (2) The random
pattern complemented is written throughout the test block. (3) The complemented pattern is
verified. (4) The random pattern is rewritten throughout the test block. (5) The random pattern
is verified.

Note: testRamRandom only tests memory in blocks, thus specifying a memory area size that
is not a multiple of the block size results in part of the memory area being untested.

Synopsis

testRamRandom [-a] [-b] [-i] [-n] [-t] [-v]

Parameters

-a Ph: Address to Start (Default = Dynamic Allocation)

-b Ph: Block Size (Default = 16 KB)

-i Pd: Iterations (Default = 1)

-n Ph: Number of Bytes (Default = 1 MB)

-t Pd: Time Delay Between Blocks in OS Ticks (Default = 1)

-v 0: Verbose Output

Example

The following example indicates a typical display when using the testRamRandom command.
