FAQ specific to the TWR-MCF51CN-KIT MQX labs


Q: What software tools do I need for TWR-MCF51CN-KIT demos and lab tutorials?

The TWR-MCF51CN-KIT requires CodeWarrior for Microcontrollers 6.2 Professional Edition (30-day evaluation available) with the 6.2.2 patch to unlock the full potential of the demos and labs.

Is version 6.2.2 necessary?  
Yes, the 6.2.2 patch contains the necessary support for the MCF51CN128.

What about CodeWarrior Special Edition

Due to the code size limitation (<64k) of Microcontroller Special Edition, the labs for the TWR-MCF51CN-KIT will not compile. 


What about CodeWarrior Basic and Standard Edition?

Those versions will work with the labs.


Q. Where is MQX Task Aware Debugging?


A: The TAD feature is only available on V2 cores or above.


Q. Why must I install the CW 6.2.2 patch after Processor Expert Update?


A:  Due to a bug in Processor Expert Update 3.05, the 6.2.2 patch must
be installed after Processor Expert. This issue was fixed in PE 3.06 or
later. If you did not install PE before the 6.2.2 patch, simply re-run the 6.2.2
patch installer again, and the problem should be solved.



Q: I'm having trouble establishing an Ethernet connection between my PC and the board.  What do I do?


1) Hit the Reset button on the board after you plug in the cable.   

2) Wait a minute or two for your computer to connect.

the board directly to your computer with an ethernet crossover cable. 
You must wait a minute or two for your computer to try to aquire a
network address.  Since you're no longer connected to your network the
computer will eventually revert to an Auto IP address on the same
subnet as board (169.254.x.x). 

3) Disable your wireless router if you have one. 

4) Disable proxy server settings in your web browser. 



When connected your computer might report limited or no connectivity, but it should still work.

If all else fails, configure your IP address manually as instructed by the quick start guide.



Q. I'm using Windows Vista and when I type telnet into a command prompt, it tells me it cannot find the program. Where is it?


A: The telnet client is not enabled by default in Windows Vista. To enable it, perform the following steps:

1. Go to Start > Control Panel > Programs and Features.
2. Select "Turn Windows features on or off"
3. Select the check box next to "Telnet Client" and hit OK.



Q. Why does the debugger say it's hitting an illegal breakpoint when executing the labs, and the Run button keeps flashing on and off?


A: This is a bug in the OSBDM and CW6.2.2 where it loses debug connection when it encounters a stop instruction. The code is still executing so it will not affect the running of the labs. A new version of OSBDM and installation instructions will be available soon.
