Building mainline U-boot and Linux kernel for Orange Pi boards

Get an ARM cross compiler

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 
$ export CC=`pwd`/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

Build the bootloader The next step is the cross compilation of the bootloader. The bootloader is the program that loads the Operating System kernel from the secondary memory to the primary memory (generally RAM) so the processor can excute it and starts the boot of the system. We suggest the use of Das U-boot: it's an open source bootloader used especially to load Linux in several architectures including ARM. You can download U-boot from Github typing the following commands:

$ git clone https://github.com/u-boot/u-boot

$ cd u-boot/
 git branch
* master

$ git checkout v2017.11 -b tmp

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.
