The detail of the error is recorded in the log file as follows.
(The following example indicates the case where an error was found in file-A.)
4-2-3 MEMORY Test
1) Test contents
This test allocates a test area in the free space in the system memory and performs Write, Read and Compare operations in the
area.
1-1) Allocate the test area
First, MEMORY Test allocates the test area in the free memory space in the system memory.
MEMORY Test tries to allocate 50% of the free space as the test area.
If it succeeds in allocating the test area, the test will go to MEMORY Test: Address Test, High/Low Test, and Burst Transfer Test.
If the test fails the memory allocation, it will try again decreasing of 1M bytes from the previous size.
The process will be repeated until it succeeds in the allocation.
However, if the allocation size comes down to 256M bytes before success, the test will recognize that it cannot acquire enough
memory for the test and the MEMORY Test will end without proceeding to the tests.
