Its high performance specification also supports a premium user experience with up to H.265 HEVC decoding of 4K video at 60 frames per second. * SOC Hisilicon Hi3798CV200 * CPU Quad-core ARM Cortex-A53 64 bit * DRAM DDR3/3L/4 SDRAM interface, maximum 32-bit data width 2 GB * USB Two USB 2.0 ports One USB 3.0 ports * CONSOLE USB-micro port for console support * ETHERNET 1 GBe Ethernet * PCIE One PCIe 2.0 interfaces * JTAG 8-Pin JTAG * EXPANSION INTERFACE Linaro 96Boards Low Speed Expansion slot * DIMENSION Standard 160×120 mm 96Boards Enterprice Edition form factor * WIFI 802.11AC 2*2 with Bluetooth * CONNECTORS One connector for Smart Card One connector for TSI Build instructions ================== .. note:: U-Boot has a **strong** dependency with the l-loader and the ARM trusted firmware repositories. The boot sequence is:: l-loader --> arm_trusted_firmware --> U-Boot U-Boot needs to be aware of the BL31 runtime location and size to avoid writing over it. Currently, BL31 is being placed below the kernel text offset (check poplar.c) but this could change in the future. The current version of U-Boot has been tested with - https://github.com/Linaro/poplar-l-loader.git:: commit f0988698dcc5c08bd0a8f50aa0457e138a5f438c Author: Alex Elder Date: Fri Jun 16 08:57:59 2017 -0500 l-loader: use external memory region definitions The ARM Trusted Firmware code now has a header file that collects all the definitions for the memory regions used for its boot stages. Include that file where needed, and use the definitions found therein Signed-off-by: Alex Elder - https://github.com/Linaro/poplar-arm-trusted-firmware.git:: commit 6ac42dd3be13c99aa8ce29a15073e2f19d935f68 Author: Alex Elder Date: Fri Jun 16 09:24:50 2017 -0500 poplar: define memory regions in a separate file Separate the definitions for memory regions used for the BL stage images and FIP into a new file. The "l-loader" image uses knowledge of the sizes and locations of these memory regions, and it can now include this (external) header to get these definitions, rather than having to make coordinated changes to both code bases. The new file has a complete set of definitions (more than may be required by one or the other user). It also includes a summary of how the boot process works, and how it uses these regions. It should now be relatively easy to adjust the sizes and locations of these memory regions, or to add to them (e.g. for TEE).
