And that is it 17 18Introduction 19============ 20 21Rock960 board family consists of Rock960 (Consumer Edition) and 22Ficus (Enterprise Edition) 96Boards featuring Rockchip RK3399 SoC. 23 24Common features implemented on both boards: 25 * CPU: ARMv8 64bit Big-Little architecture, 26 * Big: dual-core Cortex-A72 27 * Little: quad-core Cortex-A53 28 * IRAM: 200KB 29 * eMMC: 16/32GB eMMC 5.1 30 * PMU: RK808 31 * SD/MMC 32 * Display: HDMI/DP/MIPI 33 * Low Speed Expansion Connector 34 * High Speed Expansion Connector 35 36Additional features of Rock960: 37 * DRAM: 2GB/4GB LPDDR3 @ 1866MHz 38 * 1x USB 3.0 type A, 1x USB 2.0 type A (host mode only), 39 1x USB 3.0 type C OTG 40 41Additional features of Ficus: 42 * DRAM: 2GB/4GB DDR3 @ 1600MHz 43 * Ethernet 44 * 2x USB 3.0 type A, 2x USB 2.0 type A (host mode only), 45 1x USB 3.0 type C OTG 46 47Here is the step-by-step to boot to U-Boot on Rock960 boards. 48 49Get the Source and prebuild binary 50================================== 51 52 > git clone https://github.com/96rocks/rkbin.git 53 > git clone https://github.com/rockchip-linux/rkdeveloptool.git 54 55Compile the U-Boot 56================== 57 58 > cd ../u-boot 59 > cp ../rkbin/rk33/rk3399_bl31_v1.00.elf ./bl31.elf 60 > export ARCH=arm64 61 > export CROSS_COMPILE=aarch64-linux-gnu- 62 > make rock960-rk3399_defconfig 63 > make 64 65Compile the rkdeveloptool 66========================= 67 68Follow instructions in latest README 69 > cd ../rkdeveloptool 70 > autoreconf -i 71 > ./configure 72 > make 73 > sudo make install 74 75Package the image 76================= 77 78Package the image for U-Boot SPL(option 1) 79-------------------------------- 80 > cd .. 81 > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin idbspl.img 82 83 Get idbspl.img in this step. 84 85Package the image for Rockchip miniloader(option 2) 86------------------------------------------ 87 > cd ../rkbin 88 > ./tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img 0x200000 89 90 > ../u-boot/tools/mkimage -n rk3399 -T rksd -d rk3399_ddr_933MHz_v1.08.bin idbloader.img 91 > cat ./rk33/rk3399_miniloader_v1.06.bin >> idbloader.img 92 93 Get uboot.img and idbloader.img in this step. 94 95Bootloader storage options 96========================== 97 98There are a few different storage options for the bootloader. 99This document explores two of these: eMMC and removable SD/MMC. 100 101Flash the image to eMMC 102======================= 103 104Flash the image with U-Boot SPL(option 1) 105------------------------------- 106Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then: 107 > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin 108 > rkdeveloptool wl 64 u-boot/idbspl.img 109 > rkdeveloptool wl 0x4000 u-boot/u-boot.itb 110 > rkdeveloptool rd 111 112Flash the image with Rockchip miniloader(option 2) 113---------------------------------------- 114Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then: 115 > rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin 116 > rkdeveloptool wl 0x40 idbloader.img 117 > rkdeveloptool wl 0x4000 uboot.img 118 > rkdeveloptool wl 0x6000 ./img/rk3399/trust.img 119 > rkdeveloptool rd 120 121Create a bootable SD/MMC 122======================== 123 124The idbspl.img contains the first stage, and the u-boot.img the second stage. 125As explained in the Rockchip partition table reference [1], the first stage 126(aka loader1) start sector is 64, and the second stage start sector is 16384. 127 128Each sector is 512 bytes, which means the first stage offset is 32 KiB, 129and the second stage offset is 8 MiB. 130 131Note: the second stage location is actually not as per the spec, 132but defined by the SPL. Mainline SPL defines an 8 MiB offset for the second 133stage. 134 135Assuming the SD card is exposed by device /dev/mmcblk0, the commands 136to write the two stages are: 137 138 > dd if=idbspl.img of=/dev/mmcblk0 bs=1k seek=32 139 > dd if=u-boot.itb of=/dev/mmcblk0 bs=1k seek=8192 140 141Setting up the kernel and rootfs is beyond the scope of this document. 142 143And that is it 144============== 145 146You should be able to get U-Boot log in console/UART2(baurdrate 1500000) 147 148For more detail, please reference [2]. 149 150[1] http://opensource.rock-chips.com/wiki_Partitions 151[2] http://opensource.rock-chips.com/wiki_Boot_option 152
