Checking DM3 Architecture Boards
2. When you need to refer to the firmware trace log, look in the log directory:
• On a Windows system, information is logged to the file DebugAngel.log in the
%INTEL_DIALOGIC_DIR%\log directory.
• On a Linux system, information is logged to the file debugangel.log in the
${INTEL_DIALOGIC_DIR}/log directory.
Command line options and configuration options for DebugAngel are provided in Chapter 12,
“DebugAngel Reference”.
4.6 Diagnosing a Control Processor or Signal
Processor Fault on a Board
This section describes how the Dlgsnapshot tool is used to capture a core dump when a Control
Processor (CP) or Signal Processor (SP) fault is detected on a DM3 board. For details about the
Dlgsnapshot tool, refer to Chapter 15, “Dlgsnapshot Reference”.
When a fault occurs, the board on which the fault occurred is stopped automatically without
interrupting the system and a core dump file is created in the log directory. The naming convention
for this file is described in Chapter 15, “Dlgsnapshot Reference”.
Windows systems: When a core dump file is generated, you can send a .zip file containing the
contents of the %INTEL_DIALOGIC_DIR%\log directory along with the Windows event viewer
system log file (*.evt) to Intel’s telecom support resources for debugging purposes.
Linux systems: When a core dump file is generated, you can send a .tar file containing the
contents of the ${INTEL_DIALOGIC_DIR}/log directory to Intel’s telecom support resources for
debugging purposes.
You can also run the Dlgsnapshot on demand from the command line. You must specify the print
buffer to be dumped. Other command line options include the AUID, processor number, logical ID,
physical slot number, PCI bus number, and PCI slot number. A description of all the command line
options is given in Chapter 15, “Dlgsnapshot Reference”.
When boards are downloaded and you run Dlgsnapshot manually, a question is posed about
running diagnostic firmware. You must confirm that you want Dlgsnapshot to stop the running
board and download diagnostic firmware.
