Testing a Low-Frequency Target Device
Motorola Testing Your Hardware Installation 2-5
2.2 Testing Your Installation of a Target Board
If you have successfully completed the test in Section 2.1, "Testing Your Installation of
the Command Converter," and you have also connected a target device such as:
• a Suite56 application development module (e.g., DSP563xx ADM),
• a Suite56 evaluation module (e.g., DSP563xx EVM), or
• your own target board,
then we recommend that you complete your installation test by typing the commands in
Example 2 -3. (The same commands work whether you are using the graphic user
interface or the command-line interface.)
Example 2 -3. Test Commands for the Target Device
> force s
> display
In contrast to the previous test, where both commands were prefixed by “c” to direct them
to the command converter, these commands are directed to the application development
module, the evaluation module, or your own target board. The first command,
force s,
resets both the command converter and the target device. The second command displays
the contents of registers on the target device.
If both commands execute successfully and, as a consequence, you see register contents,
then you can be sure that your hardware installation is correct. If you encounter difficulty
at this point, then check whether the cable between the command converter and the target
device is working properly. If your cable is sound and your target device is a Suite56
product (e.g., Suite56 ADM or EVM), then contact your Motorola distributor for help in
determining whether your target board is defective and requires replacement.
2.3 Testing a Low-Frequency Target Device
For any low-frequency target device (i.e., less than 2MHz), you must set the command
converter and the Suite56 ADS debugger software to the proper serial clock frequency. To
do so, use the
host command with the option clock followed by the frequency, as in
Example 2 -4.
The default radix of the Suite56 ADS debugger is hexadecimal. Consequently, to express
a frequency in decimal digits, we prefix it by this character:
‘.
Example 2 -4. Setting Low Frequencies in Suite56 Tools
> host clock ‘32 ; sets the frequency to 32 kHz
> host clock $32 ; sets the frequency to 50 kHz
