USB bulk loopback example on BF527

Hi all,

I'm very new to this area and am having difficulties getting basic things up and running with the Blackfin. I'm working with a Bluetechnix CM-BF527 module. I'm trying to get the bulk_loopback_app_bf527 example for the ADSP-BF527 EZ-KIT Lite working with it. I'm using Visual DSP++ 5.0 Update 8. When I try and run the program it gets as far as the adi_usb_CoreInit() function. When it attempts to set the endpoint descriptor (line 1310 of adi_usb_core.c) it jumps to IDLE _unknown_exception_occured.

 

Has anyone encountered this before? Any ideas what's happening?

Any help would be greatly appreciated.
