    Hi Snehal


    Just to update the forum case.

    The missing steps from the RBO page are the steps below:


    1.Step to convert the sof to rbf. You could use the command below to convert the sof.

    quartus_cpf -c -o bitstream_compression=on soc_system.sof soc_system.rbf


    2.Missing u-boot.scr could be gotten from the gsrd page.

    https://releases.rocketboards.org/2025.03/gsrd/c5_gsrd/u-boot.scr


    3.Place both rbf and the u-boot.scr in the sdcard partition 1 (sdfs)


    Regards

    Jingyang, Teh

Hi


The ddr in the hardware you are using is having a 512MB DDR as where the GSRD for the devkit is having 1GB.

Please change the device tree arch/arm/dts/socfpga_cyclone5_socdk.dts to


memory {

name = "memory";

device_type = "memory";

reg = <0x0 0x20000000>; /* 1GB */

};


Regards

Jingyang, Teh
