The Ettus UHD framework adopted for the umTRX only supports GigE (simple_gemac). A reworked, Wishbone-compliant 10/100 Ethernet MAC is included in the OpenRISC SoC project on Opencores. It has been ported to the Digilent Atlys board, which has a Spartan-6 FPGA. http://www.chokladfabriken.org/projects/orpsoc-atlys I'll begin the port of this Ethernet MAC (a cleaned-up version of the 10/100 core on OpenCores) to the UmTRX and test it on Close-Haul's SP-605 Spartan-6 eval. board. I'm not quite sure how long this task will take, but this feature falls into the "nice-to-have-but-not-urgent" category.

I suppose it would also be possible to multiplex in the simple_gemac with this 10/100 core and set the mode from the ZPU via the Wishbone interface. There is a tri-mode Ethernet MAC that Ettus used to use on the USRP2, but I've never been able to make much sense of it. If you have suggestions for a better way to add 10/100 support, I'm definitely interested in hearing them. I'm not all that familiar with UHD, so you probably know better than I do. Perhaps Thomas could comment? -Robin -- Robin Coxe | Close-Haul Communications, Inc. | Boston, MA +1-617-470-8825
