Greetings !

I am trying to build stand alone u-boot for my "stm32f769 discovery board". But when I initiate make command I am getting the below error .

Please help me out to resolve this issue.

Hi,

it seens the cross-compiler ARMv7 is not defines or not installed....

do you have selected the U-Boot configuration (make <board>_defconfig) ?

for compelte steps, see the latest documentation:
