I have re-tested Codewarrior+PT60 and I can't find any problems with a basic program.
I suggest you try the following:
What exactly is the hardware you are using - do you have a picture or web reference?
Can you provide a zip file of your project exported from Codewarrior and I will see if I can find a reason for the problem.
Note: The nearest chip I have is a PT60 so I can only test on that but I believe the devices are very similar.
According to the schematic you provided you haven't connected all the power supply and ground connections. These are necessary for reliable (or at all) operation. This is especially true during programming when there are current spikes.
For reference I have attached the test circuit I use.
If you refer to the data sheet (2.2.1 Power (VDD, VSS)) it also recommends additional power supply bypass which I have not included in the test circuit.
according to your response,I try it again.But I'm failed again. USBDM programmer can program application into PA60.
but it can't be debugged through USBDM. is there other reasons ,for example,my project or codewarrior?
