Setting up the JTAG connector for a MC56F8006demo board

[lincharles]

Hi all,

I am trying to download applications from CodeWarrior 56800/E V8.2.3 onto a MC56F8006demo board via a parallel-to-JTAG converter. I am running CodeWarrior on a 32-bit Vista computer. Whenever I press the debug button, I receive an error of "cssprotocolplugin: unknown protocol error". I have tried the following tips from a previous thread, http://forums.freescale.com/freescale/board/message?board.id=CWDSPCOMM&message.id=697&query.id=11033..., but the error persists.

  - "Enable Legacy Plug and Play" is checked for my parallel port

  - The parallel port registration key, winxp2.reg is added

  - The mode of my parallel port is set to bi-directional

  - The address of the parallel port is set using commands "config cc Parallel:0x0378" and "config save"

  - The voltage coming out of my parallel port from my desktop is 5v

The log of my session says:

check_min_version(serverh=0,*version)
  api version: 00000004 00000005
config_chain(serverh=0,cc=0,count=1,*devlist,*generic)
  devlist: Holo
reset_to_debug(serverh=0,cc=0)
  ERROR(39): Subcore error encountered during multicore operation

Is there any other configuration need to be done before I can use a JTAG connector to download applications?

Thanks in advance,

Charles

Most of the suggestions you followed were for Windows XP systems. I do not know what the situation is for Vista, but I know how that Vista does handle drivers a bit differently.

You seem to have done all of the right things, so the only thing I can suggest is that you try the set-up on a system running Windows XP. I know, that is not the best suggestion given the lack of resources these days, but it would at least point out if the Vista was the culprit.

Honestly, is the accepted solution to this problem to uninstall Vista & install XP!?!

I'm having the same issue. It seems that no matter what address I point the command converter to, the error comes back as "ERROR(39): Subcore error encountered during multicore operation". 

What does that error actually mean? Can we not find the root of the problem and have it fixed for good?

Cheers,

Greg

I tried running on an XP computer and everything work just fine now. Thanks for your assistance Tom.

I scouted around the forums, and found some more information on parallel port solutions, which may be of help. The thread is:
