make menuconfig
Compile o kernel
make uImage modules
ATENÇÃO
Algumas versões do kernel Linux retornam erro ao tentar gerar a uImage. Ex:
kankin-cubie-a20 linux # make uImage modules CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h make[1]: 'include/generated/mach-types.h' is up to date. CALL scripts/checksyscalls.sh CHK include/generated/compile.h CHK kernel/config_data.h Kernel: arch/arm/boot/Image is ready Kernel: arch/arm/boot/zImage is ready multiple (or no) load addresses: This is incompatible with uImages Specify LOADADDR on the commandline to build an uImage /storage01/usr/src/linux-sunxi/arch/arm/boot/Makefile:79: recipe for target 'arch/arm/boot/uImage' failed make[1]: *** [arch/arm/boot/uImage] Error 1 /storage01/usr/src/linux-sunxi/arch/arm/Makefile:305: recipe for target 'uImage' failed make: *** [uImage] Error 2
Para sanar tal problema, tente gerar a imagem especificando a variável ${LOADADDR}:
make uImage LOADADDR=0x70008000
Instale o kernel
cp arch/arm/boot/uImage /boot/
make modules_install
