CDC on KL27Z256

Since updating form KSDK1.1 I'm having big problems with project implementing CDC virtual com using MKL27Z256.

I am not able to successfully move from the bare metal demo on FRDMKL27Z  (uses MKL27Z64) to my own board using an MK27Z356VMP4.

I really would prefer use processor expert (and now FreeRTOS) as I already have many components configured from before the update disaster.

Unfortunately the FSL_USB_CDC_Device component which looked just the job does not support the  KL27 family ??

 

Even when starting a new project from scratch the reuslts were the same,  I could get the project to compile and run on target but the USB would not enumerate.

A USB sniffer suggests there was no response to requests, as though the function to return device descriptor was not being called 

 

Any help / working demo would be gratefully received.

 

am using KDS 3.2 and have tried KSDS 1.2 and KSDK1.3. with applied KDS eclipse updates.

 

Thanks

Glenn
