MT I Program Test MT I
6.5.9 Program Test
CPU32Diag>MT I
MT I moves a program segment into RAM and executes it. The implementation of this is:
1. The program is moved into the RAM, repeating it as many times as necessary to fill
the available RAM (i.e., from Start Address to Stop Address-8). Only complete
segments of the program are moved. The space remaining from the last program
segment copied into the RAM to Stop Address-8 is filled with NOP instructions.
Attempting to run this test without sufficient memory (around 400 bytes) for at least
one complete program segment to be copied causes an error message to be printed
out: INSUFFICIENT MEMORY.
2. The last location, Stop Address, receives an RTS instruction.
3. Finally, the test performs a JSR to location Start Address.
4. The program itself performs a wide variety of operations, with the results frequently
checked and a count of the errors maintained. locations are reported in the same
fashion as any memory test failure (refer to paragraph 6.8.13).
EXAMPLE
After the command is entered, the display should appear as follows:
I MT Program Test....................Running ---------->
If the operator has not allowed enough memory for at least one program segment to be
copied into the target RAM, then the following error message is printed. To avoid this,
make sure that the Stop Address is at least 388 bytes ($00000184) greater than the Start
Address.
I MT Program Test....................Running ---------->
Insufficient Memory
PASSED
If the program (in RAM) detects any errors, then the location of the error and other
information is displayed.
I MT Program Test....................Running ---------->..... FAILED
(error-related information)
If no errors occur, then the display appears as follows:
I MT Program Test....................Running ----------> PASSED
