There are a few app notes on using USB, and one app note on DMA (AN52705), but I am unaware of one that covers exactly what you are looking for. The DMA app note was just recently released (1/13).
Have you reviewed any of the existing DMA & USB app notes?
Yes, I have combed through all app notes but nothing covers cut-through USB mode. It is clear that the firmware needs to setup the DMAC to "prime" the endpoint with data and that the DMAC needs to send more data to the USB block as data is being sent to the host (USB IN EP). It is, however, completely undocumented HOW to configure the TDs to work with cut-through mode.
I am trying to figure this out the hard way but i would very much appreciate if an example could be produced that would cut down on the guesswork.
