| 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. |
