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
