如何挂载已经编译好的kernel.img

kernel.img只能刷哦，不能想system那样挂载

楼主可以看看这个文件arch/arm/Makefile：

1. 332 kernel.img: zImage
   
2. 333     $(Q)$(srctree)/mkkrnlimg $(objtree)/arch/arm/boot/zImage $(objtree)/kernel.img >/dev/null
   
3. 334     @echo '  Image:  kernel.img is ready'
   
4. 335
   
5. 336 %_kernel.img: %.dtb zImage
   
6. 337     $(Q)cat $(objtree)/arch/arm/boot/zImage $(objtree)/arch/arm/boot/dts/$*.dtb > $(objtree)/zImage-dtb && \
   
7. 338     $(srctree)/mkkrnlimg $(objtree)/zImage-dtb $(objtree)/kernel.img >/dev/null && \
   
8. 339     rm -f $(objtree)/zImage-dtb
   
9. 340     @echo '  Image:  kernel.img (with $*.dtb) is ready'
   
10. 341
    
11. 342 LOGO := $(notdir $(wildcard $(srctree)/logo.bmp))
    
12. 343 %.img: %.dtb kernel.img $(LOGO)
    
13. 344     $(Q)$(srctree)/resource_tool $(objtree)/arch/arm/boot/dts/$*.dtb $(LOGO)
    
14. 345     @echo '  Image:  resource.img (with $*.dtb $(LOGO)) is ready'

了解一下kernel.img和zImage的格式
