1Description 2=========== 3 4Poplar is the first development board compliant with the 96Boards Enterprise 5Edition TV Platform specification. 6 7The board features the Hi3798C V200 with an integrated quad-core 64-bit 8ARM Cortex A53 processor and high performance Mali T720 GPU, making it capable 9of running any commercial set-top solution based on Linux or Android. 10 11It supports a premium user experience with up to H.265 HEVC decoding of 4K 12video at 60 frames per second. 13 14 SOC Hisilicon Hi3798CV200 15 CPU Quad-core ARM Cortex-A53 64 bit 16 DRAM DDR3/3L/4 SDRAM interface, maximum 32-bit data width 2 GB 17 USB Two USB 2.0 ports One USB 3.0 ports 18 CONSOLE USB-micro port for console support 19 ETHERNET 1 GBe Ethernet 20 PCIE One PCIe 2.0 interfaces 21 JTAG 8-Pin JTAG 22 EXPANSION INTERFACE Linaro 96Boards Low Speed Expansion slot 23 DIMENSION Standard 160×120 mm 96Boards Enterprice Edition form factor 24 WIFI 802.11AC 2*2 with Bluetooth 25 CONNECTORS One connector for Smart Card One connector for TSI 26 27At the start of the boot sequence, the bootROM executes the so called l-loader 28binary whose main role is to change the processor state to 64bit mode. This 29must happen prior invoking the arm trusted firmware: 30 31 l-loader --> arm_trusted_firmware --> u-boot 32 33How to build 34============ 35 36Code Locations 37-------------- 38 39- ARM Trusted Firmware: 40 `link <https://github.com/ARM-software/arm-trusted-firmware>`__ 41 42- l-loader: 43 `link <https://github.com/Linaro/poplar-l-loader.git>`__ 44 45- u-boot: 46 `link <http://git.denx.de/u-boot.git>`__ 47 48Build Procedure 49--------------- 50 51- Fetch all the above 3 repositories into local host. 52 Make all the repositories in the same ${BUILD\_PATH}. 53 54- Prepare the AARCH64 toolchain. 55 56- Build u-boot using poplar_defconfig 57 make CROSS_COMPILE=aarch64-linux-gnu- poplar_defconfig 58 make CROSS_COMPILE=aarch64-linux-gnu- 59 60- Build atf providing the previously generated u-boot.bin as the BL33 image 61 make CROSS_COMPILE=aarch64-linux-gnu- all fip SPD=none PLAT=poplar 62 BL33=u-boot.bin 63 64- Build l-loader (generated the final fastboot.bin) 65 1. copy the atf generated files fip.bin and bl1.bin to l-loader/atf/ 66 2. export ARM_TRUSTED_FIRMWARE=${ATF_SOURCE_PATH) 67 3. make 68 69Install Procedure 70----------------- 71 72- Copy l-loader/fastboot.bin to a FAT partition on a USB pen drive. 73 74- Plug the USB pen drive to any of the USB2 ports 75 76- Power the board while keeping S3 pressed (usb_boot) 77 78The system will boot into a u-boot shell which you can then use to write the 79working firmware to eMMC. 80 81Boot trace 82========== 83 84Bootrom start 85Boot Media: eMMC 86Decrypt auxiliary code ...OK 87 88lsadc voltage min: 000000FE, max: 000000FF, aver: 000000FE, index: 00000000 89 90Entry boot auxiliary code 91 92Auxiliary code - v1.00 93DDR code - V1.1.2 20160205 94Build: Mar 24 2016 - 17:09:44 95Reg Version: v134 96Reg Time: 2016/03/18 09:44:55 97Reg Name: hi3798cv2dmb_hi3798cv200_ddr3_2gbyte_8bitx4_4layers.reg 98 99Boot auxiliary code success 100Bootrom success 101 102LOADER: Switched to aarch64 mode 103LOADER: Entering ARM TRUSTED FIRMWARE 104LOADER: CPU0 executes at 0x000ce000 105 106INFO: BL1: 0xe1000 - 0xe7000 [size = 24576] 107NOTICE: Booting Trusted Firmware 108NOTICE: BL1: v1.3(debug):v1.3-372-g1ba9c60 109NOTICE: BL1: Built : 17:51:33, Apr 30 2017 110INFO: BL1: RAM 0xe1000 - 0xe7000 111INFO: BL1: Loading BL2 112INFO: Loading image id=1 at address 0xe9000 113INFO: Image id=1 loaded at address 0xe9000, size = 0x5008 114NOTICE: BL1: Booting BL2 115INFO: Entry point address = 0xe9000 116INFO: SPSR = 0x3c5 117NOTICE: BL2: v1.3(debug):v1.3-372-g1ba9c60 118NOTICE: BL2: Built : 17:51:33, Apr 30 2017 119INFO: BL2: Loading BL31 120INFO: Loading image id=3 at address 0x129000 121INFO: Image id=3 loaded at address 0x129000, size = 0x8038 122INFO: BL2: Loading BL33 123INFO: Loading image id=5 at address 0x37000000 124INFO: Image id=5 loaded at address 0x37000000, size = 0x58f17 125NOTICE: BL1: Booting BL31 126INFO: Entry point address = 0x129000 127INFO: SPSR = 0x3cd 128INFO: Boot bl33 from 0x37000000 for 364311 Bytes 129NOTICE: BL31: v1.3(debug):v1.3-372-g1ba9c60 130NOTICE: BL31: Built : 17:51:33, Apr 30 2017 131INFO: BL31: Initializing runtime services 132INFO: BL31: Preparing for EL3 exit to normal world 133INFO: Entry point address = 0x37000000 134INFO: SPSR = 0x3c9 135 136 137U-Boot 2017.05-rc2-00130-gd2255b0 (Apr 30 2017 - 17:51:28 +0200)poplar 138 139Model: HiSilicon Poplar Development Board 140BOARD: Hisilicon HI3798cv200 Poplar 141DRAM: 1 GiB 142MMC: Hisilicon DWMMC: 0 143In: serial@f8b00000 144Out: serial@f8b00000 145Err: serial@f8b00000 146Net: Net Initialization Skipped 147No ethernet found. 148 149Hit any key to stop autoboot: 0 150starting USB... 151USB0: USB EHCI 1.00 152scanning bus 0 for devices... 1 USB Device(s) found 153USB1: USB EHCI 1.00 154scanning bus 1 for devices... 4 USB Device(s) found 155 scanning usb for storage devices... 1 Storage Device(s) found 156 scanning usb for ethernet devices... 1 Ethernet Device(s) found 157 158USB device 0: 159 Device 0: Vendor: SanDisk Rev: 1.00 Prod: Cruzer Blade 160 Type: Removable Hard Disk 161 Capacity: 7632.0 MB = 7.4 GB (15630336 x 512) 162... is now current device 163Scanning usb 0:1... 164=> 165 166
