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 | |
