how to connect XS1-L1-64 to cypress's CY7C68013A?
We want to connect XS1-L1-64 to cypress's CY7C68013A, anybody can give me some advice?
Check out this proj. http://www.xcore.com/projects/netstamp
It uses a CY8xxxx with a L2, at least close to what you want.

Probably not the most confused programmer anymore on the XCORE forum.

I am just using SPI at the momemnt for NetStamp, thats the plan although I am having issus with my xmos kits this morning which is preventing me grr..
Later we wuld do something more elaborate like built a digital block that supports L1 4 wire LLink protocol..

hope G4 + CY7C68013A will also appear.
i am very interested to see a credit card sized board with G4 and easy full/high speed USB (micro) connector on it.

Wouldn't it be better to use an L2 chip, and implement the USB interface on that? The G4 doesn't need another chip (apart from the PHY).
you thinks it would be better to use software implementation for USB?
why not to link L{1,2}/G4 with cypress chip and have more program space on xmos?

Peripheral functions implemented in software is one of the XMOS selling points.
Yes, you are right.
May be you can comment why Opal Kelly products use Cypress + FPGA? I assume that USB could be implemented directly on FPGA too, right?

The amount of logic required and design effort might be excessive, especially for high-speed USB. There is a full-speed USB 2.0 implementation in Open Cores.

Often it comes down to drivers. The big issue with USB is not implementing the hardware rather having cross platform usb drivers on the otherside!
