Below are working steps to get a reliable CanBus working on the PI by cross compiling with Ubuntu. I use it with CoDeSys run-time which has a full CanOpen Master/Slave, J1939 Manager, and DeviceNet Scanner.

###Working directory for compiling and files
export WORKING_DIR=${HOME}/rpi2
###Number of processors to use during compiling (N+1)
export NUM_PROCESSORS=5
###PI IP ADDRESS
export PI_IP=192.168.10.104
###PI USERNAME
export PI_USER=root
###Get Required APPS to compile
sudo apt-get install gcc-arm-linux-gnueabi make ncurses-dev git dh-autoreconf
###Required of 64bit OS
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
###Make direcotry for source files and compiler
cd ${HOME}
sudo mkdir -p $WORKING_DIR
cd $WORKING_DIR
sudo chmod og+w .
###Get the Get the kernel source
git clone
https://github.com/raspberrypi/linux.git
###Get the Get cross compiler tools
git clone --depth 1 git://github.com/raspberrypi/tools.git
export KERNEL_SRC=$WORKING_DIR/linux
###Get config.gz from RPI copy to kernel source
scp root@192.168.10.104:/proc/config.gz config.gz
zcat config.gz > .config
mv .config $KERNEL_SRC
###Change to Kernel source DIR
cd $KERNEL_SRC
###Set KERNEL VERSION FOR REST OF Command
export KERNEL_VER=$(make kernelversion)
###Compile new Config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- oldconfig -j${NUM_PROCESSORS}
####Make any new changes in kernel settings
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- menuconfig -j${NUM_PROCESSORS}
