Rock/Booting Linux
Contents
Requirement
- a radxa rock board(full version or lite version)
- a desktop/laptop running Windows(XP 32/64bit, Windows 7 32/64 bit)
- a micro usb cable, one side plugged in to the OTG port of radxa rock, the other side plugged in to the usb port on desktop/laptop
Install the toolchain
Install ARM toolchain and building kernel related pacakges if you don't have them on your host.
sudo apt-get install gcc-arm-linux-gnueabihf sudo apt-get install lzop libncurses5-dev export ARCH=arm export CROSS_COMPILE=arm-linux-gnueabihf-
Build the kernel
git clone -b wip/rockchip-3.0-radxa-rock https://github.com/linux-rockchip/rockchip-3.0.git make rk3188_radxa_rock_defconfig make
Generate the ramdisk
git clone https://github.com/radxa/initrd.git cd initrd find . ! -path "./.git*" | cpio -H newc -ov > ../initrd.img cd ..
Generate the boot.img
wget http://dl.radxa.com/rock/tools/linux/mkbootimg chmod +x mkbootimg ./mkbootimg --kernel rockchip-3.0/arch/arm/boot/Image --ramdisk initrd.img -o boot.img
Next step
Now you refer flash the image to flash the generated boot.img to "boot" partition of your radxa rock board. And download a prebuilt rootfs or make your own rootfs. You will get a basic linux system boot into ramdisk and then switch root to real rootfs.
