Hello, maybe this is a stupid question, but what is needed to connect an external processor like the Blackfin BF532 to a ethernet MAC like the opencore MAC with wishbone interface or the Leon GRETH with AMBA interface? Has this been done before? Perhaps code even available? Background: There are nice uC Linux boards out there like the Blackfin One (BFONE). With all parts at least in 0.5mm pitch QFP, they are solderable for advanced amateurs. However the BF532 is low on devices, like no ethernet MAC or CAN Controller. For the MAC, the BFONE uses the DM9000 non-pci ethernet mac. However the part is hard to get and needs a lot of wiring. Putting the MAC in an FPGA and using a more readily available phys chip would be compelling. The FPGA could provide other functionallity too. uclinux code for the GRETH is also already available.
