We need to append the device tree blob to zImage (CONFIG_ARM_APPENDED_DTB option) until we can use U-Boot device tree support.
mkbootimg --kernel kernel.img --ramdisk initramfs.cpio -o boot.img

The device will reboot and you will see the linux kernel booting with GPIO, UART and SMP support.

Linux Kernel 3.17

Status

What currently works in Linux mainline:

  • UART
  • SPI
  • I2C
  • GPIOs / LEDs
  • USB
  • SD/MMC
  • Ethernet


What remains to be done:

  • DRM Display driver / LCD controller
  • HDMI / TV OUT drivers
  • NAND flash support

Download

Get linux-next kernel tree, default config and initramfs.cpio.

git clone --depth 1 git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
cd linux-next
wget http://www.sntech.de/rockchip/rockchip_defconfig -O arch/arm/configs/rockchip_defconfig
wget http://www.sntech.de/rockchip/initramfs.cpio

Build kernel

We have to build two files:

  • zImage (the kernel)
  • rk3188-radxarock.dtb (the device tree blob)


export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
make rockchip_defconfig
make -j8 zImage dtbs

Create boot image

We need to append the device tree blob to zImage (CONFIG_ARM_APPENDED_DTB option) until we can use U-Boot device tree support.

cat arch/arm/boot/zImage arch/arm/boot/dts/rk3188-radxarock.dtb > zImage-dtb

Create the boot.img using mkbootimg (Rockchip version).

mkbootimg --kernel zImage-dtb --ramdisk initramfs.cpio -o boot.img

Flash boot image

Flash boot.img using either rkflashtool or upgrade_tool:

rkflashtool w boot < boot.img
rkflashtool b
upgrade_tool di -b boot.img
upgrade_tool rd
