Hi I am newbie and have been designing a simple DIO project with a CY7C64215 device. I have programmed on the CY3664 DVK and then migrated to the CY3664-28SSOP flex on my board with great success. However when I programmed my device (Programmer tells me it has been successfull) I do not get the USB to work. My code is not pretty and is pretty much the bulk example. Any advise on where to look would be appreciated.
Hi again, I have resolved this issue, I'm off to have a fight with my PCB manufacturer who have missed off some of my thermal breaks!
