    Hi

    for the questions:

    1) The layer sheet is attached.

    2) It's the newest rocketboard GSRD for cycloneVsoc.

    3) Since I want to use the baremetal system,I dont think it would be useful for I always use the SPL to start my board.

    But the Uboot I use is 2020_07 version of altera-opensource/u-boot-socfpga.

    Please let me know if you need any other information.
