Problem in executing CDC Demo Program in M52223EVB and CW 5.9.0

Hi!

I'm trying to transmit data between PC and M52223EVB via USB (J1 plug-in). I try to use cdc-demo in CMXUSB example program package. When I make the project I receive the following error:

Link Error: Undefined: "_start"

For some reason I couldn't install Windows DDK to my PC with XP SP3. Is that the reason of the error? Is there a possibility that I can use CDC Demo without DDK?

Thanks in advance,

Teoman

Did you try the flash programmer utility for the mcf52223 MCU?

DDK utility is not needed to run CDC

Windows will ask for INF file provided with the ZIP as soon as USB device is recognized

Probably the DDK you're referring to is the Windows Studio project that needs DDK to recompile the HID source code, which at runtime is not needed at all.

Hope this helps
