Build Android Uboot failed

Why not compile Uboot? Install Cross Compiler for U-Boot

You need to install gcc-linaro-aarch64-linux-gnu- and not gcc-linaro-aarch64-none-elf-

$ wget
$ sudo mkdir /opt/toolchains
$ sudo tar -xjf gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux.tar.bz2 -C /opt/toolchains

I set everything according to the instructions. The first line in the screenshot I tried from odroid-c

You can have a try following command

# make CROSS_COMPILE=/opt/toolchains/gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux/bin/aarch64-linux-gnu- 

Thanks terry!!! Build Uboot successfully :+1:

build android failed

Try again with below command

export PATH=$PATH:/opt/toolchains/gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux/bin

I’m not able to build uboot with android oreo for VIM1 using these instructions:

Do you know why?

Did you install the aarch64-linux-gnu-cpp tool? Can you describe in detail the steps you perform?
