    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 changes looks good in the device tree.

What is the new error message that you are getting?

Did the logs show the DDR size define in the device tree size to be 512MB?


Regards

Jingyang, Teh
