export ARCH=riscv
export CROSS_COMPILE=riscv64-unknown-linux-gnu-

编译 bootloader

编译 boot0 spl

编译opensbi

book@100ask:~/eLinuxCore_dongshannezhastu/opensbi$ make PLATFORM=thead/c910 PLATFORM_RISCV_ISA=rv64gcxthead  SUNXI_CHIP=sun20iw1p1
book@100ask:~/eLinuxCore_dongshannezhastu/opensbi$ cp  platform/thead/c910/firmware/fw_jump.bin ../

编译 uboot

book@100ask:~/eLinuxCore_dongshannezhastu/u-boot$ make sun20iw1p1_defconfig
book@100ask:~/eLinuxCore_dongshannezhastu/u-boot$ make -j8
book@100ask:~/eLinuxCore_dongshannezhastu/u-boot$ cp u-boot-sun20iw1p1.bin ../

编译kernel和设备树

编译内核

book@100ask:~/eLinuxCore_dongshannezhastu/linux$ make sun20iw1p1_d1_defconfig
book@100ask:~/eLinuxCore_dongshannezhastu/linux$ make Image  -j8
book@100ask:~/eLinuxCore_dongshannezhastu/linux$ cp arch/riscv/boot/Image ../

• 打包生成特定格式

#buildroot kernel boot images.
mkbootimg --kernel  Image  --ramdisk  ramdisk.img --board  d1-nezha_min --base  0x40200000 --kernel_offset  0x0 --ramdisk_offset  0x01000000 -o  boot.img

编译设备树文件

book@100ask:~/eLinuxCore_dongshannezhastu/linux$ make dtbs
  DTC     arch/riscv/boot/dts/board.dtb
book@100ask:~/eLinuxCore_dongshannezhastu/linux$ cp  arch/riscv/boot/dts/board.dtb ../

编译内核模块

book@virtual-machine:~/eLinuxCore_dongshannezhastu/linux$ make modules -j8

分阶段打包

打包boot_package.fex

dragonsecboot -pack boot_package.cfg
