Poplar: Initial commit for Poplar E-96Boards
The board features the Hi3798C V200 with an integrated quad-core
64-bit ARM Cortex A53 processor and high performance Mali T720 GPU,
making it capable of running any commercial set-top solution based on
Linux or Android. 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
The platform boot sequence is as follows:
l-loader --> arm_trusted_firmware --> u-boot
Repositories:
- https://github.com/Linaro/poplar-l-loader.git
- https://github.com/Linaro/poplar-u-boot.git
U-Boot is also upstream in the project's master branch.
Make sure you are using the correct branch on each one of these
repositories. The definition of "correct" might change over time (at
this moment in time this would be the "latest" branch).
Build Line:
