1 Marvell U-Boot Build Instructions
2 =================================
4 This document describes how to compile the U-Boot and how to change U-Boot configuration
8 1. Install required packages:
10 # sudo apt-get install libssl-dev
11 # sudo apt-get install device-tree-compiler
12 # sudo apt-get install swig libpython-dev
14 2. Set the cross compiler:
16 # sudo apt-get install gcc-aarch64-linux-gnu
17 # export CROSS_COMPILE=aarch64-linux-gnu-
19 3. Clean-up old residuals:
23 4. Configure the U-Boot:
25 # make <defconfig_file>
27 - For the Armada-70x0/80x0 DB board use "mvebu_db_armada8k_defconfig"
28 - For the Armada-80x0 MacchiatoBin use "make mvebu_mcbin-88f8040_defconfig"
29 - For the Armada-3700 DB board use "make mvebu_db-88f3720_defconfig"
30 - For the Armada-3700 EspressoBin use "make mvebu_espressobin-88f3720_defconfig"
32 5. Configure the device-tree and build the U-Boot image:
34 For the Armada-70x0/80x0 DB board compile u-boot and set the required device-tree using:
36 # make DEVICE_TREE=<name>
39 Compilation with "mvebu_db_armada8k_defconfig" requires explicitly exporting DEVICE_TREE
40 for the requested board.
41 By default, u-boot is compiled with armada-8040-db device-tree.
42 Using A80x0 device-tree on A70x0 might break the device.
43 In order to prevent this, the required device-tree MUST be set during compilation.
44 All device-tree files are located in ./arch/arm/dts/ folder.
46 For the EspressoBin board with populated eMMC device use
47 # make DEVICE_TREE=armada-3720-espressobin-emmc
49 For other DB boards (MacchiatoBin, EspressoBin without soldered eMMC and 3700 DB board)
50 compile u-boot with just default device-tree from defconfig using:
55 The u-boot.bin should not be used as a stand-alone image.
56 The ARM Trusted Firmware (ATF) build process uses this image to generate the
57 flash image. See TF-A Build Instructions for Marvell Platforms for more details at:
58 https://trustedfirmware-a.readthedocs.io/en/latest/plat/marvell/armada/build.html
62 To update the U-Boot configuration, please refer to doc/README.kconfig
65 Permanent ethernet MAC address
66 -------------------------------
67 Prior flashing new U-Boot version (as part of ATF image) it is suggested to backup
68 permanent ethernet MAC addresses as they are stored only in U-Boot env storage (SPI or eMMC).
69 Some boards like EspressoBin have MAC addresses printed on sticker. Some boards got assigned
70 only one address other may also more than one. To print current MAC addresses run:
78 MAC addresses 00:51:82:11:22:00, 00:51:82:11:22:01, 00:51:82:11:22:02, 00:51:82:11:22:03
79 and F0:AD:4E:03:64:7F are default hardcoded values found in Marvell's and Armbian U-Boot
80 forks and therefore *not* unique. Usage of static hardcoded MAC addresses should be avoided.
81 When original address is lost (e.g. erased by Armbian boot scripts for EspressoBin) it is
82 suggested to generate new random one.
84 After flashing new U-Boot version it is suggested to reset U-Boot env variables to default
85 and then set correct permanent ethernet MAC addresses.
88 # setenv ethaddr XX:XX:XX:XX:XX:XX
89 # setenv eth1addr XX:XX:XX:XX:XX:XX
90 # setenv eth2addr YY:YY:YY:YY:YY:YY
91 # setenv eth3addr ZZ:ZZ:ZZ:ZZ:ZZ:ZZ
95 Where value for ethaddr is required permanent ethernet MAC address and values for ethNaddr
96 are optional per-port MAC addresses. When optional ethNaddr variables are not defined then
97 they are inherited from required ethaddr variable. eth1addr contains MAC address for the
98 wan port, other for particular lan ports.
100 Recent Linux kernel versions use correct permanent ethernet MAC address from U-Boot env as
101 U-Boot will inject it into kernel's device-tree.
