Trouble Shooting the Command Converter
command converter during ADS system initialization and universal command converter
reset. If a revision is issued for the monitor firmware, an environment variable must be
defined to specify the filename of the revised monitor. The specified file will be loaded
into the command converter instead of the standard monitor program. The variable which
must be defined is CC56000, where “56000” is replaced with name of the DSP family in
use, and the defined value is the fully-specified filename of the revised monitor software.
For example,
DOS, in AUTOEXEC.BAT:
SET CC56300=C:\ADS\REVISIONS\MONITOR.LOD
UNIX, with C shell, in .login or .cshrc:
setenv cc56300 /ads/revisions/monitor.lod
UNIX, with Bourne shell, in .profile:
cc56300=/ads/revisions/monitor.lod
export cc56300
specifies that, for the GUI56300, the standard DSP56300 family universal command
converter monitor code is to be replaced by the code in the file
ADS\REVISIONS\MONITOR.LOD
.
To verify that the monitor file is loading correctly, start the ADS program and enter the
following commands:
force s
display v
The monitor revision will be displayed. If the error ‘Unable to reset Command Converter’
is issued, make sure the correct path is specified in the definition of CC56x00.
2.3 Trouble Shooting the Command Converter
To ensure the command converter is connected correctly to the host card, there are several
commands that are directed specifically to the command converter. The first is:
cforce r
This command will reset the ADS chain throughout the host card, up to the command
converter. Another helpful command is:
cdisplay x:0#10
This command displays x memory locations 0 through 10 of the command converter. The
values in memory are irrelevant, the fact that memory from the command converter can be
read indicates that you are communicating correctly with the command converter. If these
