求助：CCSProtocolPlugin:CCS Cable disconnected Cable, CCS, disconnected, 求助

大家好，我用的是DSP56F807EVMUM评估板，刚才还能在CW中DEBUG,有事中断了一会，重新上电后却不能下载程序和DEBUG了，在CW中点击DEBUG,弹出CCSProtocalPlugin:CCS Cable disconnected的窗口。但发现DSP中的程序还在运行，因为程序中，在定时中断启动的AD采样完成后，对评估板上的LED小灯状态进行了翻转控制。现在LED灯还在闪烁。前段时间，我在自己做的控制板上也遇到相同的情况，前一天晚上还能正常调试，偶尔会弹出上述窗口，当第二天完全不能DEBUG了。是不是DSP烧坏了？该如何解决？谢谢！

你检查你的链接了，接口使劲拧一下，不行的话就这样：
(A) In windows XP/2000, the parallel port dialog checkbox entitled
"Enable Legacy Plug and Play" should be checked. This setting is
located in the Control Panel-->System-->Hardware->Device
Manager->Ports->Printer Port (LPTX) dialog.

(B) Here are the steps to modify the parallel port registry key appropriately:

1. save the winxp1.reg file to your hard drive
2. make sure you are logged in as the system administrator
3. run the winxp1.reg file (by double clicking on it)
4. A question will be displayed "Are you sure you want to add the  information in c:\winxp1.reg to the registry?"
5. Click the Yes button
6. A message will display "Information in c:\winxp1.reg has been successfully entered into the registry."
7. restart your computer to apply the new changes


(C)The Command Converter/Server attempts to get it's parallel port information from the BIOS of your computer. Sometimes this process won't work, for instance if you are using and add-on card, or if your BIOS is simply incompatible. In these instances the port address must be set manually.

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.[
