Here is a sample makefile for an out of kernel module that you can use
to create a custom rtdm module.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
#this should be the path to your patched kernel source that has the
ipipe patches and Xenomai links applied
#if you are using the O option when building the kernel (build takes
place out of tree) use that directory
XENO_KDIR := <path to patched kernel source>
#This is only needed if you are cross compiling, if you are not cross
compiling then leave these blank
CROSS_COMPILE=arm-linux-gnueabihf-
ARCH=arm
PWD := $(shell pwd)
#name of your module that you are compiling
obj-m+=rtdm_hello.o
all:
make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) M=$(PWD) -C
$(XENO_BUILD) modules
clean:
make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) M=$(PWD) -C
$(XENO_BUILD) modules
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
For your purposes you don't need the CROSS_COMPILE and ARCH options
you can omit those so your make lines should look like this,
make M=$(PWD) -C $(XENO_BUILD) modules
I'll be creating a simple sample driver, maybe similar to how it's
done in LDD3 and post it. This is all depending on when I get time to
do so , no time line lol
