Multilink and Vista problems

JeffB — Wed, 29 Jul 2009 09:36:16 GMT

I recently upgrade to a computer with Vista and am now having a few problems with the PE Multilink CF. I have installed the latest drivers and I can get it to work with CF Flasher but have trouble with the CodeWarrior.

Most time when I click on debugger it get a message that the "Coldfire PE Protocol Adapter: No USB connection found". But sometimes, it magically works. Other times I have to unplug the Multilink from the USB port for a few minutes and then reconnect.

When it does work, if I kill the debug thread, it will not work the next time I try to start the debugger.

I had installed the CodeWarrior 7.1 before I updated the drivers.

Has anyone had this trouble or a solution?

I once had a similar problem after upgrading my PC to Vista, but I never understood how it happened - see description in this thread:

Hello Jeff,

>>get a message that the "Coldfire PE Protocol Adapter: No USB connection found".

I had this type of issue with CW when CF Flasher is started (closing of the CF Flasher helped .

BTW:
I have very often not repetitive issues with CW Flasher.
But CF Flasher always works perfectly and faster.

Best regards,

Hi Jeff,

You may find the following FAQ useful:

http://www.pemicro.com/faqs/faq_view.cfm?ID=103

It was written for the CF Flasher utility, but applies to CodeWarrior as well.

Best regards,

Getting close but not there yet.

PE Micro indicated that to run under Vista that a new version of unit_cfz.dll needs to be in the CFFlasher directory and in C:\Window\System32.

I did that and CFFlasher appears to be working.

I found an older version of the dll in C:\Program Files\Freescale\CodeWarrior for ColdFire V7.1\bin\Plugins\Support\Coldfire\pemicro.

I replaced that dll with a new one and the Multilink works a little better in Codewarrior. I still have to click the run button 2 or 3 times before it will find the device.

I'll keep at it, if anyone else had an idea I'm all ears.
