- Introduction
- ============
- RK3328 key features we might use in U-Boot:
- * CPU: ARMv8 64bit quad-core Cortex-A53
- * IRAM: 36KB
- * DRAM: 4GB-16MB dual-channel
- * eMMC: support eMMC 5.0/5.1, suport HS400, HS200, DDR50
- * SD/MMC: support SD 3.0, MMC 4.51
- * USB: USB2.0 EHCI host port *2
- * Display: RGB/HDMI/DP/MIPI/EDP
- evb key features:
- * regulator: pwm regulator for CPU B/L
- * PMIC: rk808
- * debug console: UART2
- In order to support Arm Trust Firmware(ATF), we need to use the
- miniloader from rockchip which:
- * do DRAM init
- * load and verify ATF image
- * load and verify U-Boot image
- Here is the step-by-step to boot to U-Boot on rk3328.
- Get the Source and prebuild binary
- ==================================
- > mkdir ~/evb_rk3328
- > cd ~/evb_rk3328
- > git clone https://github.com/ARM-software/arm-trusted-firmware.git
- > git clone https://github.com/rockchip-linux/rkbin
- > git clone https://github.com/rockchip-linux/rkflashtool
- Compile ATF
- ===============
- > cd arm-trusted-firmware
- > make realclean
- > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3328 bl31
- Compile U-Boot
- ==================
- > cd ../u-boot
- > make CROSS_COMPILE=aarch64-linux-gnu- evb-rk3328_defconfig all
- Compile rkflashtool
- =======================
- > cd ../rkflashtool
- > make
- Package image for miniloader
- ================================
- > cd ..
- > cp arm-trusted-firmware/build/rk3328/release/bl31.bin rkbin/rk33
- > ./rkbin/tools/trust_merger rkbin/tools/RK3328TRUST.ini
- > ./rkbin/tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img
- > mkdir image
- > mv trust.img ./image/
- > mv uboot.img ./image/rk3328evb-uboot.bin
- Flash image
- ===============
- Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
- > ./rkflashtool/rkflashloader rk3328evb
- You should be able to get U-Boot log message in console/UART2 now.
