平台：rk3399 （与平台关系不大）
内核 ：linux5.15
下一个linux5.15的内核，编译的时候
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j6 rk3399-rock960.img
目标rk3399-rock960.img 需要在arch/arm64/boot/dts/rockchip/ 目录下存在rk3399-rock960.dts文件 ，如果不存在，可以使用其他的dts文件作为目标。
错误提示1：（没法编译img这个目标）
make: *** No rule to make target 'rk3399-rock960.img'. Stop.
解决1：
修改arch/arm64/Makefile，在文件末尾增加一段（其他的内容不变）
MAKE_MODULES ?= y
%.img:
ifeq ("$(CONFIG_MODULES)$(MAKE_MODULES)$(srctree)","yy$(objtree)")
$(Q)$(MAKE) rockchip/$*.dtb Image.lz4 modules
else
$(Q)$(MAKE) rockchip/$*.dtb Image.lz4
endif
$(Q)$(srctree)/scripts/mkimg --dtb $*.dtbCLEAN_DIRS += out
CLEAN_FILES += boot.img kernel.img resource.img zboot.img
再执行上面的make命令，该错误就没有了。
错误提示2：没有mkimg命令
解决：
从原（rk3399）sdk的内核中拷贝过来，这是个脚本文件。
cp ../kernel/scripts/mkimg scripts/

解决：
1. 从原sdk中拷贝c文件（当然可以直接拷贝二进程执行文件，拷贝二进制就不用修改makefile了）

2.修改 scripts/Makefile ，让他能够编译改c文件
hostprogs-always-$(CONFIG_ARCH_ROCKCHIP) += resource_tool
再次make，就没有错误了。
但是问题是，仍然没有生成boot.img
通过查看mkimg文件的流程，发现还缺少一个命令
解决：
从原来的sdk拷贝一个过来，再次make，就成功生成了boot.img。
mkbootimg是一个python脚本，内容如下：
