COMMS TEST ROUTINES
Tests 22, 23 and 24 are all associated with the comms processor. As discussed at the start of the
test software section, the comms processor is requested to enter its test routines when the test
software initialises. The comms LED should flash twice to indicate that it is waiting for a command
from the fifo.
There are 4 standard error screens associated with the comms/kernel processor interaction rather
than the tests themselves. In these error screens pressing the re-run key (key 3) attempts to re-run
the previous test and pressing the continue key (key 4) will continue with the test or return to the test
select menu as appropriate.
1) If the kernel has waited for a message from the comms which has not arrived then the
following screen will be displayed:
Timeout waiting for re-run >
COMMS response Press to continue >
2) If the kernel processor received data from the comms which did not match anything it was
expecting then the following screen will be displayed:
Bad data received re-run >
from COMMS Press to continue >
3) If the Comms processor received data from the kernel which did not match anything it
was expecting then the following screen will be displayed:
Bad data was received re-run >
by COMMS Press to continue >
4) If the Kernel processor attempts to send some data to the comms and fails because the
fifo reports it is full then the following screen is displayed:
FIFO1 is reporting it re-run >
is full Press to continue >
