USB HID Demo on FRDM-K66F

Hi,

 

I am testing USB HID Generic demo(BM version) and works fine..

Then, I am using Wizard 2.x in KDS 3.2.0 to generate my own project by choosing "include all driver", no RTOS option.

After that, I copied required USB stack and files from demo project, compile it, link it to generate *.elf fine. All work fine.

But, when I download it to my FRDM-K66F and run it, I got the error code==0x02(USB Busy) when I call USB_DeviceClassInit(CONTROLLER_ID, &g_UsbDeviceHidConfigList, &g_UsbDeviceHidGeneric.deviceHandle)). I check CONTROLLER_ID is 2.

Looks like it can't allocate memory for my USB handle...

Can anyone tell me where the problem can be, related to environment setting, like OS?

 

Thanks,

 

Christie
