Orange Pi R1 Plus is a Rockchip RK3328 based SBC by Xunlong. This device is similar to the NanoPi R2S, and has a 16MB SPI NOR (mx25l12805d). The reset button is changed to directly reset the power supply, another detail is that both network ports have independent MAC addresses. The device tree and description are taken from kernel v6.3-rc1. Reviewed-by: Kever Yang <kever.yang@rock-chips.com> Signed-off-by: Tianling Shen <cnsztl@gmail.com> |

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.
