      1 Introduction
      2 ============
      3 
      4 The RK3399-Q7 (Puma) is a system-on-module featuring the Rockchip
      5 RK3399 in a Qseven-compatible form-factor.
      6 
      7 RK3399-Q7 features:
      8 	* CPU: ARMv8 64bit Big-Little architecture,
      9 		* Big: dual-core Cortex-A72
     10 		* Little: quad-core Cortex-A53
     11 		* IRAM: 200KB
     12 	* DRAM: 4GB-128MB dual-channel
     13 	* eMMC: onboard eMMC
     14 	* SD/MMC
     15 	* GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY
     16 	* USB:
     17 		* USB3.0 dual role port
     18 		* 2x USB3.0 host, 1x USB2.0 host via onboard USB3.0 hub
     19 	* Display: HDMI/eDP/MIPI
     20 	* Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF)
     21 	* NOR Flash: onboard SPI NOR
     22 	* Companion Controller: onboard additional Cortex-M0 microcontroller
     23 		* RTC
     24 		* fan controller
     25 		* CAN
     26 
     27 Here is the step-by-step to boot to U-Boot on rk3399.
     28 
     29 Get the Source and build ATF/Cortex-M0 binaries
     30 ===============================================
     31 
     32   > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
     33   > git clone git://git.theobroma-systems.com/rk3399-cortex-m0.git
     34 
     35 Compile the ATF
     36 ===============
     37 
     38   > cd arm-trusted-firmware
     39   > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
     40   > cp build/rk3399/release/bl31.bin ../u-boot/bl31-rk3399.bin
     41 
     42 Compile the M0 firmware
     43 =======================
     44 
     45   > cd ../rk3399-cortex-m0
     46   > make CROSS_COMPILE=arm-cortex_m0-eabi-
     47   > cp rk3399m0.bin ../u-boot
     48 
     49 Compile the U-Boot
     50 ==================
     51 
     52   > cd ../u-boot
     53   > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all
     54 
     55 Package the image
     56 =================
     57 
     58 Creating a SPL image for SD-Card/eMMC
     59   > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl_mmc.img
     60 Creating a SPL image for SPI-NOR
     61   > tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin spl_nor.img
     62 Create the FIT image containing U-Boot proper, ATF, M0 Firmware, devicetree
     63   > make CROSS_COMPILE=aarch64-linux-gnu- u-boot.itb
     64 
     65 Flash the image
     66 ===============
     67 
     68 Copy the SPL to offset 32k for SD/eMMC, offset 0 for NOR-Flash and the FIT
     69 image to offset 256k card.
     70 
     71 SD-Card
     72 -------
     73 
     74   > dd if=spl_mmc.img of=/dev/sdb seek=64
     75   > dd if=u-boot.itb of=/dev/sdb seek=512
     76 
     77 eMMC
     78 ----
     79 
     80 rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
     81 help of the Rockchip loader binary.
     82 
     83   > git clone https://github.com/rockchip-linux/rkdeveloptool
     84   > cd rkdeveloptool
     85   > autoreconf -i && ./configure && make
     86   > git clone https://github.com/rockchip-linux/rkbin.git
     87   > ./rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
     88   > ./rkdeveloptool wl 64 ../spl_mmc.img
     89   > ./rkdeveloptool wl 512 ../u-boot.itb
     90 
     91 NOR-Flash
     92 ---------
     93 
     94 Writing the SPI NOR Flash requires a running U-Boot. For the sake of simplicity
     95 we assume you have a SD-Card with a partition containing the required files
     96 ready.
     97 
     98   > load mmc 1:1 ${kernel_addr_r} spl_nor.img
     99   > sf probe
    100   > sf erase 0 +$filesize
    101   > sf write $kernel_addr_r 0 ${filesize}
    102   > load mmc 1:1 ${kernel_addr_r} u-boot.itb
    103   > sf erase 0x40000 +$filesize
    104   > sf write $kernel_addr_r 0x40000 ${filesize}
    105 
    106 
    107 Reboot the system and you should see a U-Boot console on UART0 (115200n8).
