- Marvell U-Boot Build Instructions
- =================================
- This document describes how to compile the U-Boot and how to change U-Boot configuration
- Build Procedure
- ----------------
- 1. Install required packages:
- # sudo apt-get install libssl-dev
- # sudo apt-get install device-tree-compiler
- # sudo apt-get install swig libpython-dev
- 2. Set the cross compiler:
- # export CROSS_COMPILE=/path/to/toolchain/aarch64-marvell-linux-gnu-
- 3. Clean-up old residuals:
- # make mrproper
- 4. Configure the U-Boot:
- # make <defconfig_file>
- - For the Armada-70x0/80x0 DB board use "mvebu_db_armada8k_defconfig"
- - For the Armada-80x0 MacchiatoBin use "make mvebu_mcbin-88f8040_defconfig"
- - For the Armada-3700 DB board use "make mvebu_db-88f3720_defconfig"
- - For the Armada-3700 EsspressoBin use "make mvebu_espressobin-88f3720_defconfig"
- 5. Configure the device-tree and build the U-Boot image:
- Compile u-boot and set the required device-tree using:
- # make DEVICE_TREE=<name>
- NOTE:
- Compilation with "mvebu_db_armada8k_defconfig" requires explicitly exporting DEVICE_TREE
- for the requested board.
- By default, u-boot is compiled with armada-8040-db device-tree.
- Using A80x0 device-tree on A70x0 might break the device.
- In order to prevent this, the required device-tree MUST be set during compilation.
- All device-tree files are located in ./arch/arm/dts/ folder.
- NOTE:
- The u-boot.bin should not be used as a stand-alone image.
- The ARM Trusted Firmware (ATF) build process uses this image to generate the
- flash image.
- Configuration update
- ---------------------
- To update the U-Boot configuration, please refer to doc/README.kconfig
