Hi Michal. Thanks for your reply.

On u-boot 2014.04 release, I don't know how to use full u-boot either. Full u-boot image of zynq enables CONFIG_OF_SEPARATE, right? I think u-boot.img does not include device tree. Should I combine u-boot.img and device tree by myself? Like this? cat u-boot.img u-boot.dtb > u-boot.img.tmp mv u-boot.img.tmp u-boot.img Or should I disable CONFIG_OF_SEPARATE? > Keep in your mind that using U-BOOT SPL is not fully supported flow. > Supported flow is fsbl->u-boot->linux.

I know this works. But in my understanding, SPL cannot use this command. My question is how SPL can load the init ramdisk. It looks like spl_load_image_fat_os() function loads "system.dtb" and "uImage". But I could not find which code loads ramdisk. Not supported yet?
