Poplar ====== Poplar is the first development board compliant with the 96Boards Enterprise Edition TV Platform specification. 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. It 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 At the start of the boot sequence, the bootROM executes the so called l-loader binary whose main role is to change the processor state to 64bit mode. This must happen prior to invoking Trusted Firmware-A: :: l-loader --> Trusted Firmware-A --> u-boot How to build ------------ Code Locations ~~~~~~~~~~~~~~ - Trusted Firmware-A: `link `__ - l-loader: `link `__ - u-boot: `link `__ Build Procedure ~~~~~~~~~~~~~~~ - Fetch all the above 3 repositories into local host. Make all the repositories in the same ${BUILD\_PATH}. - Prepare the AARCH64 toolchain. - Build u-boot using poplar_defconfig .. code:: bash make CROSS_COMPILE=aarch64-linux-gnu- poplar_defconfig make CROSS_COMPILE=aarch64-linux-gnu- - Build atf providing the previously generated u-boot.bin as the BL33 image .. code:: bash make CROSS_COMPILE=aarch64-none-elf- all fip SPD=none PLAT=poplar BL33=u-boot.bin - Build l-loader (generated the final fastboot.bin) 1. copy the atf generated files fip.bin and bl1.bin to l-loader/atf/ 2. export ARM_TRUSTED_FIRMWARE=${ATF_SOURCE_PATH) 3. make Install Procedure ----------------- - Copy l-loader/fastboot.bin to a FAT partition on a USB pen drive. - Plug the USB pen drive to any of the USB2 ports - Power the board while keeping S3 pressed (usb_boot) The system will boot into a u-boot shell which you can then use to write the working firmware to eMMC.
