PROCESSOR-SDK-AM335X: Build Driver Module Fail

WOODY

Hi Team,

I have a question about how to build kernel module correctly.

Makefile is as below :

CROSS_COMPILE := arm-none-linux-gnueabihf-
ARCH := arm
KERNEL_DIR := /lib/modules/$(shell uname -r)/build


MODULE_NAME = intc_gpio
obj-m += $(MODULE_NAME).o

all:
	make ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNEL_DIR) M=$(PWD) modules
clean:
	make -C $(KERNEL_DIR) M=$(PWD) clean

Sample C Code

#include <linux/init.h>
#include <linux/module.h>

MODULE_DESCRIPTION("Hello_world");
MODULE_LICENSE("GPL");

static int hello_init(void)
{
 printk(KERN_INFO "Hello world !\n");
 return 0;
}

static void hello_exit(void)
{
 printk(KERN_INFO "Bye !\n");
}

module_init(hello_init);
module_exit(hello_exit);

The build error is as below

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- -C /lib/modules/5.4.0-150-generic/build M=/home/plcnet/workspace_ax5/example_driver modules

According to the error message, I check the missing file and try to supplement it.

However, what followed was more error messages.

Do you know how to fix it ? Do I need to install or upgrade packages to Make it ?

Thanks.

Hey Woody,

Could you please list the contents of the "/lib/modules/5.4.0-150-generic/build"? if you are attempting to use -C you need to make sure that the given directory contains linux headers. The Yocto project has some nice documentation on building out-of-tree modules if you need some help with that: https://docs.yoctoproject.org/kernel-dev/common.html#working-with-out-of-tree-modules

Regards,

Randolph

Hi Sapp,

Below is the content of the path, I have created a soft-link for "include/asm" using "$ ln -s asm-generic asm" to solve the first problem.

But what followed was more error messages.

Woody, you've listed the contents of the include directories you've linked but I'm still not certain about the structure of the top level directory you are specifying with "-C" (/lib/modules/5.4.0-150-generic/build). Could you please list the contents of that directory.

Woody,

Thanks, though, what is this build directory? Did you generate it or did some tool do it? I'm a little concerned that it just contains links to what appears to be a proper headers directory one level above.

Was the headers directory above built using the correct architecture? Some header files are generated as part of the build process and may end up containing architecture specific code.

Regards,

Randolph

Hi Sapp,

I am not sure how the build directory comes. I did not use any tool to generate it.

If I want to re-generate these build directory, how should I do?

Thanks.

Woody,

Are you compiling this on target or are you cross-compiling this? If you're cross-compiling this, are you using the "Processor SDK SITARA AM335X Linux Package" assets?

Randolph
