Revision as of 14:26, 14 April 2014

Build Linux Mainline

WARNING: this Linux kernel is intended for developers only. A lot of things are not working yet: I2C, SPI, USB, framebuffer, HDMI driver, SD/MMC, NAND Flash, etc.

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

export ARCH=arm && export CROSS_COMPILE=arm-linux-gnueabihf-
make rockchip_defconfig
make -j8 rk3188-radxarock.dtb
make -j8 zImage

Flash boot image

cat arch/arm/boot/zImage arch/arm/boot/dts/rk3188-radxarock.dtb > kernel.img
mkbootimg --kernel kernel.img --ramdisk initramfs.cpio -o boot.img
upgrade_tool di -b boot.img
upgrade_tool rd

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