I recently got a BeagleWire board to play with, which is an Lattice FPGA with SDRAM. The FPGA configuration can be build with devel/icestorm and beside being slow should be possible on the Beaglebone itself. The most usefull way to hook up the FPGA, seems to be via memory bus. -- B.Walter http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
