Hello

Which version of CodeWarrior are you running?
To retrieve that information:
 - Start the IDE
 - Select "Help" -> "About Metrowerks CodeWarrior""
 - Click on "Installed products"
 - product currently installed are written on the top of the dialog.

Which debug connection are you using (simulator, Multilink, .....)?

Which component did you open to get Trace data?

Hello

I still need to figure out which version you are using.

Can you please do the following:
 - Start the IDE
 - Select "Help" -> "About Metrowerks CodeWarrior""
 - Click on "Installed products"

 - Click on "Save As and save information in a text file.

 - Zip that text file and attach it to the thread.

If I understand you well, you are running your code on a real hardware board and you are using a USB Multilink cable as connection.

And you are running your code on a HCS12GC64. Am I right?

Is the crash happening also with a project created from a stationery or only with your project?

Hello

Trace component should be working with CW HC12 V4.5.

I would suggest you to submit a service request through our web page.

Please attach the installed plug in document and a project reproducing the trouble.

You can use the Pack and Go wizard to collect all info needed to forward a project. Use Help -> "Pack and Go" to start the Pack and Go wizard.

hi all,

I gave up this feature after few failure trials.
Months later, I accidentally make the trace function not hang anymore. I found out that it hangs at bclr a bit value of certain port, when the port is not initialised. After the port is initialised at startup, either clear it or $FF it, the trace function will not hang anymore. I wonder why such a small step could hang the whole program.

Anyway, now comes my question. When I halt the running target, the trace sometimes( most of the times) display nothing. I was using Automatic trigger mode ie no specific trigger/ breakpoint defined. I was using assembly language.

while in another example provided by codewarrior which is in C code, whenever I halt the running target the trace window shows all the relevant instructions.

can anyone help me? How do I set up the debugger to display instruction whenever I halt the running target in trace window?

thanks for your help.

hi all,

I notice some strange record from trace window. I attached the dump file for your reference.

It shows many 'Instruction outside application', which are all invalid addressess. But after that the program execution will back to normal. Can anyone explain what's going on?

It also tag some valid address that's never been executed. I put a breakpoint at certain location, the debugger never stop at that particular breakpoint, but in trace window that particular address is recoreded! Is this trace feature reliable?

thanks everyone!
