kernel 的生成

kernel 的生成

从Release_to_customer.sh中可以看到，当flash类型选择为nand，并且不开启fastboot模式时，在kernel目录下执行：

# make infinity2m_spinand_ssc011a_s01a_minigui_defconfig

Release_to_customer.sh中kernel的脚本内容如下所示：

#build kernel
cd ${RELEASEDIR}/kernel
declare -x ARCH="arm"
declare -x CROSS_COMPILE="arm-linux-gnueabihf-"
if [ "${flashtype}" = "nor" ]; then
    if [ "${fastboot}" = "fastboot" ]; then
        make infinity2m_ssc011a_s01a_fastboot_defconfig
    else
        make infinity2m_ssc011a_s01a_minigui_defconfig
    fi

else
    if [ "${fastboot}" = "fastboot" ]; then
        make infinity2m_spinand_ssc011a_s01a_minigui_fastboot_defconfig
    else
        #make infinity2m_spinand_ssc011a_s01a_minigui_defconfig
        make ${KERNEL_DEFCONFIG}
    fi

fi
#make clean
make -j16

# vi arch/arm/configs/infinity2m_spinand_ssc011a_s01a_minigui_defconfig

可以得知，目标dtb为 arch/arm/boot/dts/infinity2m-spinand-ssc011a-s01a-display.dtb，目标dts为 arch/arm/boot/dts/infinity2m-spinand-ssc011a-s01a-display.dts。
