Altera have told me it is not possible to perform a multiple device configuration (typically done by hooking up the nCE/nCEO pins of the individual FPGAs) when using local update mode (update over ethernet). Does anyone know why it isn't possible? It is not reasonable for a board with 10 FPGAs to have 10 separate ethernet connections, and having to update a set of these boards in the field ...

Hi Does anyone have any experiences with connecting a MAC rather than a PHY to a spartan(3e). I don't know yet whether to use a microblaze or my own state machine to connect to the ethernet. For microblaze, xilinx cores seem to want just an external PHY but surely a MAC would offload more stuff from the FPGA. Any thoughts appreciated. Regards Colin

Hi all, I am having some difficulties working with the DMA of the ethernet mac. I've downloaded a ref. design of web-server over the virtex-2P (with ppc 405) - it works well. However I would like to add a DMA -> which means that every packet that is recieved will be directly written to the DIMM that is on board (xupv2p E.B.). I tried to read the docs explaining the proceadure, BUT GOT LOST.
