8.10 SELFTEST - Perform On-board Selftest
Format: SELFTEST
This command performs a test of the on-board functions of the CPU
board. It may only run if no other tasks are created. If there are any other
tasks, no selftest will be made and an error will be reported. The selftest
tests the memory of the CPU board and all devices on the board.
The following tests are performed in this order:
1. I/O Test
This function tests the access to and the interrupts from the
DUSCC. If the DUSCC cannot generate interrupts, an error will be
reported. This test also checks if reading from and writing to the
floppy disk controller and the SCSI controller proceeds as
expected.
2. Memory Test on the Memory of the Current Task
The following procedures are performed:
1) Byte Test
2) Word Test
3) Longword Test
All passes of the memory test perform pattern reading and writing
as well as bit shift tests. If an error occurs while writing to or
reading from memory, it will be reported. Dependent on the size of
the main memory, this test may last a different amount of time
(count about one minute per megabyte).
3. Clock Test
If the CPU does not receive timer interrupts from the PI/T 68230,
an error will be displayed. This ensures that VMEPROM could
initialize the PI/T 68230 properly and the interrupts from the PI/T
are working
CAUTION: During this process, all memory is cleared.
