@tihmstar Thanks, no need. I ordered two on Crowdsupppy and I have enough FPGA boards to just get something running using a RISC-V core with LiteX. Hardest part is to find time for all of this 🫣 The plan was anyway to do an open source KNX SoC with a RISC-V, a few peripherals and a TP1 MAC on a small iCE40 FPGA or something.
