Code Warrior LPT1, and Connection Server problems (MC56F801x)

liquidsquid — Thu, 12 Jul 2007 09:58:40 GMT

Ok, my computer did not have a parallel port, and I am a little upset that the low-cost JTAG solution requires that... I had to go purchase an expansion card that allowed me to use a PCI-x to PCI bridge, and then to two serial and one parallel ports. It appears at first glance to be an acceptable card, though I hope it is not the problem.

I have the MC56F8013 Demo board, and I am simply trying to run the example LED flasher.

The parallel port init utility claims it cannot find LPT1, and does not execute properly. I am assuming that I don't necessarily nead this to perform JTAG operations, it is just to get the printer port in the right mode and exits. This I blame on the expansion card drivers.

I open the example project, and click the debug button.
The CodeWarrior connection server loads fine, and points to LPT1 (in the console) This is the content of the console window right now:

So it looks happy. However when I try to debug, I get an error message dialog:

CCSProtocolPlugin : CCS: Command Converter Not Present.

What do I do now? I can clearly see the connection accepted, then it immediatly closes again. It seems to be on the Metrowerks side.

I cannot get beyond this point.

Thanks for your help!

Thanks to Fiona at Freescale for helping out, here is the process that worked for me:

1) Run CW and try to debug to your DSP board connected to the PCI

parallel port. It will fail as expected.

2) Right click on the CCS icon in your SysTray and select Show CCS

Console.

3) at the prompt, type:

delete all

...then press [ENTER], then type:

config cc lpt:0x<address of your parallel port

For instance, if you're card is at ECF8, type:

config cc lpt:0xECF8 [ENTER]

If you don't know the address of your parallel port, you can find out in

Window's hardware settings. On Windows 2000, go to:

Start->Settings->Control Panel->System->Hardware(tab)->Device

Start->Settings->Manager->Ports

You will see your parallel port here. Double-click on it and go to the

Resources tab. The first Input/Output address listed is the address to

give CCS. Mine is 0378. It may be different for your setup.

Try to debug. It should now work.

If it does, execute this final command to save your current CCS

settings:

config save [ENTER]

This will write out the settings to a config file, which will be

automatically loaded by CCS for future debugging sessions.

If using the address in hex does not work, please try the address in

decimal. The syntax is slightly different:

Instead of

config cc lpt:0x378

use

config cc lpt:888

You can convert the port address using the Calculator in Windows in

scientific mode.

Hope this helps!

It helped. Thanks!
