First I am trying to learn and am in no way an expert.
I have searched and searched for a walkthrough on how to compile LKMs for my
pandaboard ES. My target is the pandaboard running Linaro 12.08. I am using
Linaro toolchain binary 12.08. My confusion comes from me not knowing where
the kernel sources are (really how to get them) and the target libraries. I
guess what I expect is the target's rootfs with kernel source to be
somewhere on my Ubuntu Host so I can link to them.
I have tried the following make file configs. But obviously, I don't have
the correct path for KERNDIR as I don't know if it even exists on my host.
And the second make file seems like a native compile.
My previous experience with buildroot:
KERNDIR=/opt/buildroot/build_arm/linux-2.6.20.7/
export CROSS_COMPILE=arm-linux-
export ARCH=arm
obj-m += pwr_led.o
all:
make -C $(KERNDIR) M=$(PWD) modules
clean:
make -C $(KERNDIR) M=$(PWD) clean
Web examples:
obj-m = foo.o
KVERSION = $(shell uname -r)
all:
make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean
Could you please set my head straight by pointing me to a webpage or briefly
walking through the steps?
Thanks,
Todd
