3.1.94 testRamAlt
Name
testRamAlt—assures addressability of memory, using a memory test block. Addressing errors
are sought by writing an alternating pattern of all zeros and all ones. This test proceeds as
follows: (1) Location (n) is written with data of all bits 0. (2) The next location (n+4) is written
with all bits. (3) Steps 1 and 2 are repeated throughout the memory block. (4) The memory is
read and verified for the correct data pattern(s) and any errors are reported.
Note: testRamAlt 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
testRamAlt [-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 testRam command.
MOTLoad> testRamAlt -v
Executing RAM Addressing: PASSED
