Hello,

When I try to build USBCDC, the resulting AXF .text does not fit into MFlash32. It overflows by 3548 bytes. Doesn't this demo run on a LPC1343?

What am I doing wrong?

Thanks

The usbcdc example seems to build fine here with LPCXpresso 3.6.2....

Can you post the contents of the whole your build log, including the overflow message?

Sorry I took so long -

I now assume that this is the error I should get with the free version which has the 8K debug limit. Is this true? I can use the release version, which is smaller than 8K.

Thanks

Why don't you activate your version to free activated version with 128k limit :confused:
