android6.0 insmod xx.ko, exec format error

jiejia — Mon, 20 Feb 2017 07:08:58 GMT

Hi,

I have a board reference to imx6q-sabresd using android_M6.0.1_2.0.0_source.tar.gz.

I am trying to port device drivers on this board.

makefile：

obj-m := sema.o
KDIR := /work/myandroid/kernel_imx/
PWD := $(shell pwd)
all:
make -C $(KDIR) ARCH=arm CROSS_COMPILE=arm-linux-androideabi- M=$(PWD) modules
clean:
$(MAKE) -C $(KDIR) M=$(PWD) clean

when insmod sema.ko：

root@sabresd_6dq:/data/local/tmp # insmod sema.ko
insmod: failed to load sema.ko: Exec format error

Hello Jia,

The question is on how to compile linux kernel module and write Makefile, Actually, it is not within our support range. Only give you some advice, help you correct your Makefile, see below, please!

---------------------------------------------Pay attention to correct path of your compiler----------------------------

obj-m := sema.o

sema-objs := sema.o
KDIR := /work/myandroid/kernel_imx/
PWD := $(shell pwd)

ARCH=arm

CROSS_COMPILE=arm-eabi-

CC=$(CROSS_COMPILE)gcc

LD=$(CROSS_COMPILE)ld
all:
make -C $(KDIR) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) M=$(PWD) modules
clean:
$(MAKE) -C $(KDIR) M=$(PWD) clean

--------------------------------------------------------------------------------------------------------------------------------------------

Try it , please!

Regards,

Weidong
