    Hello! This short document contains some information about running Linux on MIPSfpga-plus system that is deployed on Terasic DE10-Lite development board with Altera MAX10 chip and SDRAM:

    Very good work indeed!

    Regarding the ahb-lite uart + ahb-lite sdram wrapper. AFAICT, they are written in Verilog. Is it ‘technically’ easy to port to an equivalent Xilinx FPGA based board? Is there a board with 32/64Mbyte SDRAM with an easy interface to hook up to.

    Regards,

    p.s.
    MIPSfpga-SOC (not mipsfpga-plus) is based on Xilinx only and uses an AHB-lite -> AXI bridge to use Xilinx IP blocks.

    Hello, ZubairLK
    Thanks for your kind words! Yes, UART and SDRAM modules of MIPSfpga-plus are platform independent. They are written on pure Verilog. So there should be no problem with porting this configuration to Xilinx boards. The only thing you have to check (and may be configure) are SDRAM timings and clock shift. The current version of SDRAM module supports only x16 memory, but this can be easily fixed.
    Sorry, but I cant help you with information about Xilinx FPGA based board with SDRAM chip on it. Because I have only Altera FPGA based boards.
