CCSprotocolPlugin: failed to correctly configure JTAG chain

[vrinda]

Hi All

im currently Working with MPC 8280 using CODEWARRIOR V8.8 , when ever i tried to connect it with USB tAP im getting a error message like "Failed to correctly configure the JTAG. and sometimes very rarely it gets connected and once JTAG cable is removed it does'nt gets connected for a long time for so many trials like 80 to 100 so on.

Now i need to know what may be the problem, and  whether it is a Hardware issue or do i need to change Code warrior settings.

I am attaching a snapshot of that particular error.

Please help me out  and Thanks in advance.

I assume that you are using Windows 7, correct? And a P&E Micro USB probe? You may want to go to the P&E Micro web site (www.pemicro.com) to download and install their latest drivers. I would also use the forum search function (the boxes at the upper right) to search for USB problems with Windows 7. There have been several threads on connection issues.

Any Freescale USB TAP interface uses P&E Microsystems drivers and hardware. I've got a DEMO9S08 board (right, it's not the same board, but bear with me) that has an integrated USB/BDM port, and an ASIC on the board with a "PE Micro" label manages the USB/BDM communications. I'd try the P&E Micro driver installation and see if it also does a firmware update.
