1 | U-Boot for Amlogic U200 |
2 | ======================= | |
3 | ||
4 | U200 is a reference board manufactured by Amlogic with the following | |
5 | specifications: | |
6 | ||
7 | - Amlogic S905D2 ARM Cortex-A53 quad-core SoC | |
8 | - 2GB DDR4 SDRAM | |
9 | - 10/100 Ethernet (Internal PHY) | |
10 | - 1 x USB 3.0 Host | |
11 | - eMMC | |
12 | - SDcard | |
13 | - Infrared receiver | |
14 | - SDIO WiFi Module | |
15 | - MIPI DSI Connector | |
16 | - Audio HAT Connector | |
17 | - PCI-E M.2 Connector | |
18 | ||
19 | Schematics are available from Amlogic on demand. | |
20 | ||
21 | Currently the u-boot port supports the following devices: | |
22 | - serial | |
23 | - Ethernet | |
24 | - Regulators | |
25 | - Clock controller | |
26 | ||
27 | u-boot compilation | |
28 | ================== | |

31 | > make u200_defconfig | |
32 | > make | |
33 | ||
34 | Image creation | |
35 | ============== | |
36 | ||
37 | Amlogic doesn't provide sources for the firmware and for tools needed | |
38 | to create the bootloader image, so it is necessary to obtain them from | |
39 | the git tree published by the board vendor: | |

52 | Download the latest Amlogic Buildroot package, and extract it : | |
53 | > wget http://openlinux2.amlogic.com:8000/ARM/filesystem/Linux_BSP/buildroot_openlinux_kernel_4.9_fbdev_20180706.tar.gz | |
