Description
memory.
The test may be for the entire RAM or NVRAM regions, or for a specified range of
values. You may also select to run the test for a set number of loops, or to loop
infinitely.

Type rt /gn 510000 5100b0 25000 and press
Results: This tests the integrity of the global non-volatile
(static) RAM between the memory range of 510000
and 5100b0 repeatedly for 25,000 times.
The system simply returns the prompt when it
successfully completes this instruction.
If the test fails, the system displays an error message
before returning to the prompt.
