u-boot configuration

[telestarx]

I've download u-boot source from https://github.com/OLIMEX/u-boot-olinuxino
and make config make

make CROSS_COMPILE=aarch64-linux-gnu- BL31=../atf/bin/bl31.bin a64-olinuxino_defconfig

and make menuconfig  and set
CONFIG_TARGET_A64_OLINUXINO=y 
CONFIG_LAST_STAGE_INIT=y

and build is OK.. but build version filesize(738kB) is smaller than download version(868kB)
and when I type 'saveenv' in u-boot command. error is displayed like below

Saving Environment to EXT4... File System is consistent
mmc write failed
