5.5 Core Updump
In some cases—such as when a ControlWave Express fails for no
apparent reason—you can upload a copy of the contents of SRAM and
SDRAM to a PC for support personnel and service engineers to
evaluate. This upload is called a “core updump.”
A core updump may be required if the ControlWave Express
spontaneously enters a watchdog state that affects all system operation.
This occurs when the system crashes as a result of a CPU timeout
(resulting from improper software operation, a firmware glitch, and so
on). In some cases, the watchdog state can recur but you cannot
logically reproduce the conditions.
The CPU’s RAM contains “crash blocks,” a firmware function provided
specifically for watchdog troubleshooting. You can view and save the
crash blocks by viewing the Crash Block Statistic Web Page (see the
Web_BSI Manual
, D5087). On request, you can forward crash block
files to our technical support personnel. If they need additional
information to evaluate the condition, the technical support group may
request a core updump. Once the core updump process generates a file,
you can forward that file to the support personnel for evaluation and
resolution.
Use the following steps to preserve the “failed state” condition at a
system crash and perform a core updump:
1.
Set switch SW2-1 on the CPU/System Controller board to
OFF
(Disable Watchdog Timer). If switch SW2-4 is
ON
, set it to
OFF
(Enable Core Updump).
Note
:
The factory default setting for switch SW2-4 is
OFF
.
2.
Wait for the error condition (typically 3F on the status LEDs or
“NOTRUN” on the optional display).
3.
Connect the ControlWave Express’s Comm Port 1 to a PC using
a half duplex null modem cable.
