Just been reading up on this project. Really love the mix of new FPGA hardware and the ability to use existing peripherals. Such a shame it's not getting much interest, I'd love to help out. Hardware is mostly my area but also some software. Also can help with testing.
Happy to cover the cost of purchasing hardware and could assemble if needed, building up SMT boards isn't a problem.
Drop me a PM if any of this would be of help
