Hi Craig,
Thanks for your reply and for relocating this thread. I am confused though as the USB device MSC is working with the BF526 kit using Crosscore 1.1 tools. This seems inconsistent with the Crosscore 1.1 release notes. Regardless, it sounds like I need to wait for uC/USB Device 1.1.0 stack in order to port my SPI driver and merge it with the USB device MSC class and the file system elements for the BF70x.
Does that sound right? Thanks, -Phil
