AN-T80020 Diagnostics Procedure
Issue 12 Feb 11 AN-T80020 49
0x4000 Series Codes (Module firmware operation)
APP_INVALID_IMAGE
0x4000
Modules:All
This test checks the application firmware in FLASH on either loading
the boot code or the application firmware. Detects a FLASH memory
fault or missing firmware. The module will stay in boot mode. If loading
application firmware, erase and try again, else return the module for
repair. If loading boot firmware, return the module for repair.
Action:Slice will not boot
APP_INVALID_IMAGE_CRC
0x4001
Modules:All
This test performs a CRC check on the firmware in FLASH on either
loading the boot code or the application firmware. Detects a FLASH
memory fault or corrupted firmware. The module will stay in boot mode.
If loading application firmware, erase and try again, else return the
module for repair. If loading boot firmware, return the module for repair.
Action:Slice will not boot
APP_BOOT_ERROR
0x4002
Modules:All Checks to see if the firmware application failed to boot the previous
time. A code is stored in memory when the boot process fails. This
code prevents further boot attempts. If the module fails to start, return it
for repair, otherwise ignore this fault.
Action:Slice will not boot
APP_STACK_FAULT
0x4003
Modules:All This test checks the stack in the background. Checks for S/W errors
that corrupt the stack. Report to ICS Triplex Technology.
Action:Slice OFFLINE
APP_SELF_TEST_FAULT
0x4004
Modules:All Declares a fault if the test task does not execute within 2 minutes (input
modules) or 30 minutes (output modules). Also set if one of the
checkpoints in the code is not run, i.e. not all expected code has run.
This is common after a poor startup or a bypass timer lockout and is
usually a secondary symptom of these or other faults. If it occurs with
no recent fault that would have caused the slice to turn off, report to
ICS Triplex Technology.
Action:Slice OFFLINE
SFIU_PI_LATE
0x4020
Modules:8442 The pulse input testing has been delayed too long. This is caused by
abnormal processing burden but may indicate a task scheduling
problem. Report to ICS Triplex Technology.
Action:Slice fault
