1 Marvell U-Boot Build Instructions 2 ================================= 3 4 This document describes how to compile the U-Boot and how to change U-Boot configuration 5 6 Build Procedure 7 ---------------- 8 1. Install required packages: 9 10 # sudo apt-get install libssl-dev 11 # sudo apt-get install device-tree-compiler 12 # sudo apt-get install swig libpython-dev 13 14 2. Set the cross compiler: 15 16 # export CROSS_COMPILE=/path/to/toolchain/aarch64-marvell-linux-gnu- 17 18 3. Clean-up old residuals: 19 20 # make mrproper 21 22 4. Configure the U-Boot: 23 24 # make <defconfig_file> 25 26 - For the Armada-70x0/80x0 DB board use "mvebu_db_armada8k_defconfig" 27 - For the Armada-80x0 MacchiatoBin use "make mvebu_mcbin-88f8040_defconfig" 28 - For the Armada-3700 DB board use "make mvebu_db-88f3720_defconfig" 29 - For the Armada-3700 EsspressoBin use "make mvebu_espressobin-88f3720_defconfig" 30 31 5. Configure the device-tree and build the U-Boot image: 32 33 Compile u-boot and set the required device-tree using: 34 35 # make DEVICE_TREE=<name> 36 37 NOTE: 38 Compilation with "mvebu_db_armada8k_defconfig" requires explicitly exporting DEVICE_TREE 39 for the requested board. 40 By default, u-boot is compiled with armada-8040-db device-tree. 41 Using A80x0 device-tree on A70x0 might break the device. 42 In order to prevent this, the required device-tree MUST be set during compilation. 43 All device-tree files are located in ./arch/arm/dts/ folder. 44 45 NOTE: 46 The u-boot.bin should not be used as a stand-alone image. 47 The ARM Trusted Firmware (ATF) build process uses this image to generate the 48 flash image. 49 50 Configuration update 51 --------------------- 52 To update the U-Boot configuration, please refer to doc/README.kconfig 53 54
