Step 3: Try Some Simple Commands To Control The Target; If The Emulation Probe Has Problems Controlling The Target - Agilent Technologies E5900B User Manual

• Check that the proper firmware is installed for this processor.
Some PowerPC chips require different firmware to be installed for different
mask revs or other slight differences of the processor. For example, the
PowerPC 603ev processor requires that the E3479 firmware be installed and
the Motorola PowerPC 603ei requires that the E3477i firmware be installed.
Step 3: Try some simple commands to control the
target
Examples of some commands are listed on page 93 and page 96.
If the emulation probe has problems controlling
the target
The emulation probe might be having problems controlling the target if you
see messages such as:
"Cannot break"
"Processor is checkstopped"
"Bad status code (0xff) received from the processor"
Or the prompt changes to "?>"
Problems controlling the target can be caused by a variety of conditions.
Typically the problem is in the configuration of the emulation probe or the
configuration of the target.
Try the following to better control your target:
• Decrease the JTAG or BDM communication speed. Some targets need
slower speeds to properly communicate.
If you are using a telnet connection or a debugger command file, use the cf
speed command (cf procck for BDM).
• Check the emulation probe configuration settings.
If you are using a telnet connection, enter the cf command to display all of
the configuration settings. Note that some emulation probes must set the
processor type with cf proc=processor_type.
• Check that the emulation probe is not restricted to real-time runs.
