Hi Jeremy, These boards both contain a spartan6 lx9, which is the same FPGA I have on my lx9 micro board. It's a smaller FPGA than the nano has, so price and/or connectivity will need to be significantly better to make it worth it. I have managed to fit a stripped down or1200 with an UART on it, but after adding the Ethernet mac it used up about 200% of the FPGA resources. With a bit of optimization though I think it won't be too hard to fit an or1k (mor1kx espresso might be a good choice considering the potential use cases) with some SPI and I2C.
As a side note, I've started working on Xilinx support in ORPSoCv3 with the intention on making it run on my LX9 microboard. Hopefully I can provide some rough estimates for resource usage after that.
