boot.img的生成过程

make -C common O=../out/target/product/g18ref/obj/KERNEL_OBJ ARCH=arm CROSS_COMPILE=arm-eabi- meson6_g18_jbmr1_taixin_defconfig -j4

 

make -C common O=../out/target/product/g18ref/obj/KERNEL_OBJ ARCH=arm CROSS_COMPILE=arm-eabi- modules

 

make -C common O=../out/target/product/g18ref/obj/KERNEL_OBJ ARCH=arm CROSS_COMPILE=arm-eabi- uImage -j8

 

cd out/target/product/g18ref/root

find . | cpio -o -H newc | gzip -9 > ../ramdisk.img

 

out/host/linux-x86/bin/mkbootimg  --kernel out/target/product/g18ref/obj/KERNEL_OBJ/arch/arm/boot/uImage  --ramdisk 

 

 

Recovery.img生成和boot.img生成区别只是：

cd $PRODUCT_OUT/recovery/root

find .| cpio -o -H newc | gzip -9 > ../../ramdisk-recovery.img
