Colorlight-FPGA-Projects

some board & modules made by Colorlight are based on Lattice ECP5 series and Xilinx XC7 series, which are supported by open source toolchain (yosys & prjtrellis & nextpnr), can be used to make very interesting project.
current focus on Colorlight i5-v7.0 and i9-v7.2, i9plus-v6.1, check get-start to see how to setup the env and program the bitstream.
the Colorlight i9-v7.2 contain a LFE5U-45F-6BG381, all GPIO already reversed, check Colorlight i9-v7.2 to see the detail.
the Colorlight i9plus-v6.1 contain a XC7A50T-FGG484, all GPIO already reversed, check Colorlight i9plus-v6.1 to see the detail.
