1 Introduction 2 ============ 3 4 RK3328 key features we might use in U-Boot: 5 * CPU: ARMv8 64bit quad-core Cortex-A53 6 * IRAM: 36KB 7 * DRAM: 4GB-16MB dual-channel 8 * eMMC: support eMMC 5.0/5.1, suport HS400, HS200, DDR50 9 * SD/MMC: support SD 3.0, MMC 4.51 10 * USB: USB2.0 EHCI host port *2 11 * Display: RGB/HDMI/DP/MIPI/EDP 12 13 evb key features: 14 * regulator: pwm regulator for CPU B/L 15 * PMIC: rk808 16 * debug console: UART2 17 18 In order to support Arm Trust Firmware(ATF), we need to use the 19 miniloader from rockchip which: 20 * do DRAM init 21 * load and verify ATF image 22 * load and verify U-Boot image 23 24 Here is the step-by-step to boot to U-Boot on rk3328. 25 26 Get the Source and prebuild binary 27 ================================== 28 29 > mkdir ~/evb_rk3328 30 > cd ~/evb_rk3328 31 > git clone https://github.com/ARM-software/arm-trusted-firmware.git 32 > git clone https://github.com/rockchip-linux/rkbin 33 > git clone https://github.com/rockchip-linux/rkflashtool 34 35 Compile ATF 36 =============== 37 38 > cd arm-trusted-firmware 39 > make realclean 40 > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3328 bl31 41 42 Compile U-Boot 43 ================== 44 45 > cd ../u-boot 46 > make CROSS_COMPILE=aarch64-linux-gnu- evb-rk3328_defconfig all 47 48 Compile rkflashtool 49 ======================= 50 51 > cd ../rkflashtool 52 > make 53 54 Package image for miniloader 55 ================================ 56 > cd .. 57 > cp arm-trusted-firmware/build/rk3328/release/bl31.bin rkbin/rk33 58 > ./rkbin/tools/trust_merger rkbin/tools/RK3328TRUST.ini 59 > ./rkbin/tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img 60 > mkdir image 61 > mv trust.img ./image/ 62 > mv uboot.img ./image/rk3328evb-uboot.bin 63 64 Flash image 65 =============== 66 Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then: 67 68 > ./rkflashtool/rkflashloader rk3328evb 69 70 You should be able to get U-Boot log message in console/UART2 now. 71
