arm linux内核编译与测试

 

 

$ sudo apt-get install build-essential ddd cpio libncurses5-dev libsdl-dev zlib1g-dev

$ wget http://www.codesourcery.com/sgpp/lite/arm/portal/package6490/public/arm-none-linux-gnueabi/arm-2010q1-202-arm-none-linux-gnueabi.bin

$ chmod +x arm-2010q1-202-arm-none-linux-gnueabi.bin

$ ./arm-2010q1-202-arm-none-linux-gnueabi.bin

$ wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.35.tar.bz2

$ tar xjf linux-2.6.35.tar.bz2

$ cd linux-2.6.35/

$ make ARCH=arm versatile_defconfig

$ make ARCH=arm menuconfig

When the menu appears, I go into the “Kernel Features” section and enable EABI support; then I exit (saving the configuration) and compile:

$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- all

$ cd ..

The result is a compressed kernel image in “./linux-2.6.35/arch/arm/boot/zImage”.
