The first step to do is getting an ARM cross compiler. We suggest the use of Linaro GCC toolchain. To download the latest release you can visit this site https://releases.linaro.org/components/toolchain/binaries/, choose a release and download the tarball gcc-linaro--x86_64_arm-linux-gnueabihf.tar.xz. Alternatively you can open a terminal and use wget command, for example to downloade the release 7.2.1-2017.11 you have to type:
$ wget https://releases.linaro.org/components/toolchain/binaries/latest-7/arm-linux-gnueabihf/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf.tar.xz
swig is required
$ wget -c wget -c releases.linaro.org/components/toolchain/binaries/7.2-2017.11/arm-linux-gnueabihf/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf.tar.xz

``bash
$ tar xvf src/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf.tar.xz

Configure and build U-boot it's easy because U-boot supports many Orange Pi boards via defconfig, so you just need to type:
$ make ARCH=arm CROSS_COMPILE={CC} distclean
$ make ARCH=arm CROSS_COMPILE={CC} <orangepi_model>_defconfig
$ make ARCH=arm CROSS_COMPILE={CC} where <orangepi_model> depends on the board that you want to use, for example for Orange Pi PC Plus it's orangepi_pc_plus. At the end of the building you will find in u-boot folder the file u-boot-sunxi-with-spl.bin. You will use this file soon for the setup of the microSD card.
