hii i am trying to compile a simple device driver and insert it on lenux system that is on the DE1-SOC board that i have
i included the files when i compile the lkm module gets generated but when i move it to the de1-soc board and try the insmod command i get an error i it cant load

when i do file hello.ko i can see that its elf 32bit arm file

but when i put on the board it says invalid module format

what i missing here i be glad for help

the make file code

Target object file

obj-m := hello.o

Cross-compiler path for ARM (BeagleBone)

CROSS_COMPILE_ARM = arm-linux-gnueabihf-

Cross-compiler path for x86 (Intel)

CROSS_COMPILE_X86 =

Target architecture (default: ARM)

ARCH ?= arm

ifeq ($(ARCH),x86_64)
# Compile for x86 (Intel)
CROSS_COMPILE := $(CROSS_COMPILE_X86)
else
# Compile for ARM (default)
CROSS_COMPILE := $(CROSS_COMPILE_ARM)
endif

Kernel directory

KERNELDIR ?= $(HOME)/linux

Current directory

PWD := $(shell pwd)

Build target for building the module

module:
$(MAKE) -C $(KERNELDIR) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) M=$(PWD) modules
@Echo “Building module for $(ARCH) architecture”

Clean target for cleaning the module build artifacts

clean:
$(MAKE) -C $(KERNELDIR) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) M=$(PWD) clean
rm -rf *.o ~ core .depend ..cmd *.ko *.mod.c .tmp_versions

Declare the targets as phony targets

.PHONY: module clean
