[Sarmad Ahmad]

Hi,

i am stundent and try to build u-boot for board cora-z7-10

I build u-boot as follows



export  ARCH=arm

export CROSS_COMPILE=gcc-7-arm-linux-gnueabihf-

export DEVICE_TREE="zynq-zc702"

make xilinx_zynq_virt_defconfig

make



I have also tried this export command from unfortunately also without success

CROSS_COMPILE=aarch64-linux-gnu



unfortunately i always get this error:
