在wsl下开发T113的主线linux（4）-编译kernel

接下来编译kernel，编译过程可能会出现缺少命令的报错，大概是下面这几个

sudo apt update
sudo apt install flex bison bc libncurses-dev

目前linux主线的最新版本并没有适配t113的相关外设驱动，虽然能启动并串口打印，但其他的一些外设并没有驱动，还不是可用的状态，所以这里选择全志D1的kernel进行修改。
GitHub - smaeul/linux at d1/allPatches include sunxi platform support and various driver fixes - GitHub - smaeul/linux at d1/allhttps://github.com/smaeul/linux/tree/d1/all

unzip linux-d1-all.zip
cd linux-d1-all

应用awboot提供的linux补丁

• linux/allow_select_d1_ccu_on_t113.patch
• linux/ccu-sun20i-make_cpux_clk_critical_for_t113.patch
• linux/second_core_support_in_platsmp.patch
• linux/d1s_t113_can_bus.patch

在arch\arm\configs\sunxi_defconfig中添加D1时钟

CONFIG_SUN20I_D1_CCU=y
CONFIG_SUN20I_D1_R_CCU=y

添加sun8i-t113.dtsi和sun8i-t113-mangopi-dual.dts设备树配置文件到arch\arm\boot\dts\
在arch\arm\boot\dts\Makefile的line:1389 处，CONFIG_MACH_SUN8I配置中添加sun8i-t113-mangopi-dual.dtb

awboot提供的sun8i-t113-mangopi-dual.dts设备树文件调试终端串口是5，需要改成uart0。

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- sunxi_defconfig
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- zImage -j4
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- dtbs

xfel spinand write 0x40000 arch/arm/boot/dts/sun8i-t113-mangopi-dual.dtb
xfel spinand write 0x80000 arch/arm/boot/zImage

 

 复位，串口成功打印内核信息，目前spinand中还没有文件系统，所以系统无法启动成功。
