The RK3399-Q7 SoM is a Qseven-compatible (70mm x 70mm, MXM-230 connector) system-on-module from Theobroma Systems, featuring the Rockchip RK3399. It provides the following feature set: * up to 4GB DDR3 * on-module SPI-NOR flash * on-module eMMC (with 8-bit interace) * SD card (on a baseboad) via edge connector * Gigabit Ethernet w/ on-module Micrel KSZ9031 GbE PHY * HDMI/eDP/MIPI displays * 2x MIPI-CSI * USB - 1x USB 3.0 dual-role (direct connection) - 2x USB 3.0 host + 1x USB 2.0 (on-module USB 3.0 hub) * on-module STM32 Cortex-M0 companion controller, implementing: - low-power RTC functionality (ISL1208 emulation) - fan controller (AMC6821 emulation) - USB<->CAN bridge controller Note that we use a multi-payload FIT image for booting and have Cortex-M0 payload in a separate subimage: we thus rely on the FIT image loader to put it into the SRAM region that ATF expects it in.

Introduction ============ The RK3399-Q7 (Puma) is a system-on-module featuring the Rockchip RK3399 in a Qseven-compatible form-factor. RK3399-Q7 features: * CPU: ARMv8 64bit Big-Little architecture, * Big: dual-core Cortex-A72 * Little: quad-core Cortex-A53 * IRAM: 200KB * DRAM: 4GB-128MB dual-channel * eMMC: onboard eMMC * SD/MMC * GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY * USB: * USB3.0 dual role port * 2x USB3.0 host, 1x USB2.0 host via onboard USB3.0 hub * Display: HDMI/eDP/MIPI * Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF) * NOR Flash: onboard SPI NOR * Companion Controller: onboard additional Cortex-M0 microcontroller * RTC * fan controller * CAN Here is the step-by-step to boot to U-Boot on rk3399. Get the Source and build ATF/Cortex-M0 binaries =============================================== > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git > git clone git://git.theobroma-systems.com/rk3399-cortex-m0.git Compile the ATF =============== > cd arm-trusted-firmware > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31 > cp build/rk3399/release/bl31.bin ../u-boot Compile the M0 firmware ======================= > cd ../rk3399-cortex-m0 > make CROSS_COMPILE=arm-cortex_m0-eabi- > cp rk3399m0.bin ../u-boot Compile the U-Boot ================== > cd ../u-boot > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all Package the image ================= > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl.img > tools/mkimage -f board/theobroma/puma_rk3399/fit_spl_atf.its \ -E rk3399_bl3x.itb Flash the image =============== Copy the SPL to offset 32k and the FIT image containing the payloads (U-Boot proper, ATF, M0 Firmware, devicetree) to offset 256k on a SD card. > dd if=spl.img of=/dev/sdb seek=64 > dd if=rk3399_bl3x.itb of=/dev/sdb seek=512 After powering up the board (with the inserted SD card), you should see a U-Boot console on UART0 (115200n8).
