我正在使用内核版本为4.9.88的iMX6S-EVK ARMV7。我正在写一些简单的内核驱动程序。我还下载了linux 4.9.88内核。但是当我编译时，出现了这个错误：
ERROR: Kernel configuration is invalid. include/generated/autoconf.h
or include/config/auto.conf are missing. Run 'make oldconfig && make
prepare' on kernel src to fix it. WARNING: Symbol version dump
./Module.symvers is missing; modules will have no dependencies and
modversions.

In file included from <command-line>:0:0:
././include/linux/kconfig.h:4:32: fatal error: generated/autoconf.h:
No such file or directory compilation terminated.
这是我的Makefile：
KERNEL ?= /home/user1/Desktop/linux
ARCH ?= arm
CROSS_COMPILE ?= arm-linux-gnueabihf-
obj-m+=hello.o
all:
make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNEL) M=$(PWD) modules
clean:
make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNEL) M=$(PWD) clean
我执行以下命令进行构建：
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
我错过了什么吗？我现在该怎么办？
