| U-Boot for Amlogic W400 |
| ======================= |
| |
| U200 is a reference board manufactured by Amlogic with the following |
| specifications: |
| |
| - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC |
| - 2GB DDR4 SDRAM |
| - 10/100 Ethernet (Internal PHY) |
| - 1 x USB 3.0 Host |
| - eMMC |
| - SDcard |
| - Infrared receiver |
| - SDIO WiFi Module |
| - MIPI DSI Connector |
| - Audio HAT Connector |
| - PCI-E M.2 Connector |
| |
| Schematics are available from Amlogic on demand. |
| |
| Currently the u-boot port supports the following devices: |
| - serial |
| - Ethernet |
| - Regulators |
| - Clock controller |
| |
| u-boot compilation |
| ================== |
| |
| > export ARCH=arm |
| > export CROSS_COMPILE=aarch64-none-elf- |
| > make w400_defconfig |
| > make |
| |
| Image creation |
| ============== |
| |
| Amlogic doesn't provide sources for the firmware and for tools needed |
| to create the bootloader image, so it is necessary to obtain them from |
| the git tree published by the board vendor: |

| > make |
| > export UBOOTDIR=$PWD |
| |
| Download the latest Amlogic Buildroot package, and extract it : |
| > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz |
| > tar xfz buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz buildroot_openlinux_kernel_4.9_fbdev_20180706/bootloader |
| > export BRDIR=$PWD/buildroot_openlinux_kernel_4.9_fbdev_20180706 |
| > export FIPDIR=$BRDIR/bootloader/uboot-repo/fip |
| |
| Go back to mainline U-Boot source tree then : |
