Hi. This is a tutorial for using CAN BUS on bananapi with bananian 15-01.

- Download and install "bananian-1501.img" into 8 GB SDCard.
- Expand the root file system using "bananian-config"

- Install missing package:
  1. apt-get install git
  2. apt-get update
  3. apt-get upgrade
  4. reboot
Copy the Code
Get last bananian available, and continu to install missing package:
  1. git clone https://github.com/Bananian/linux-bananapi
  2. apt-get install build-essential u-boot-tools uboot-mkimage
  3. apt-get install libusb-1.0-0 libusb-1.0-0-dev git wget fakeroot kernel-package zlib1g-dev libncurses5-dev
  4. apt-get install subversion
Copy the Code
- Build kernel:
  1. cd linux-bananapi
  2. make menuconfig
Copy the Code
- Exit without saving when menu appears
  1. zcat /proc/config.gz > /root/linux-bananapi/.config
  2. make uImage modules
  3. make INSTALL_MOD_PATH=output modules_install
Copy the Code
- At this step, kernel should be compiled and "Module.symvers" should be available
- Then rename modules and firmware provide by Bananian, and replace by the new one.
  1. mv /lib/modules /lib/modules.old
  2. mv /lib/firmware /lib/firmware.old

  3. mv /root/linux-bananapi/output/lib/modules /lib/modules
  4. mv /root/linux-bananapi/output/lib/firmware /lib/firmware
Copy the Code
- Same for uImage:
  1. mount /dev/mmcblk0p1 /mnt
  2. cd /mnt
  3. mv uImage uImage.old
  4. mv /root/linux-bananapi/arch/arm/boot/uImage /mnt
  5. reboot
Copy the Code
- Create link for further build:
  1. cd /lib/modules/3.4.104/
  2. ln -s /root/linux-bananapi build
  3. cd ~
Copy the Code
- Get Can4Linux and build it:
  1. svn checkout https://svn.code.sf.net/p/can4linux/code/trunk can4linux-code
  2. cd /root/can4linux-code/can4linux/
  3. make TARGET=BANANAPI
Copy the Code
- Install module for each startup of the board:
  1. insmod can4linux.ko
  2. cp can4linux.ko /lib/modules/3.4.104/kernel/net/can/
  3. depmod -A -v
  4. modprobe -v can4linux
  5. echo "" >> /etc/modules ; echo "can4linux" >> /etc/modules
  6. reboot
Copy the Code
- Build CAN example
  1. apt-get install swig
  2. apt-get install python-dev
  3. cd can4linux-code/can4linux-examples/
Copy the Code
- At this step, if you want to use python sample, you should make some modification:

edit file "Makefile" and replace line 190:
  $(CC) $(CFLAGS) -c -fpic -I/usr/include/python \
by
  $(CC) $(CFLAGS) -c -fpic -I/usr/include/python2.7 \

- Build example:
  1. make
  2. make pyCan
Copy the Code
- Update CAN speed and device in file "pyCan-example.py"

ex:
  1. # setting the device number
  2. device = 0
  3. defaultBaudrate = '250'
Copy the Code
- Connect CAN transceiver and CAN bus, and check with for example:
  1. python pyCan-example.py
Copy the Code
That's all

With this method, kernel version is "Linux bananapi 3.4.104" instead of "Linux bananapi 3.4.104+", because i was unable to find same sources than Bananian 15-01   , but CAN bus work !

Feel free to comment or update.

Enjoy.



I did ok till here

126 root@bananapi ~ # make INSTALL_MOD_PATH=output modules_install                                                

make: *** No rule to make target `modules_install'.  Stop.

took me a long time...first time i tried compiling a kernal i think me and the screen just became friends.
any ideas were i go from here?

  very goog tut

thanks

Since:

The INSTALL_MOD_PATH option specifies the directory where the full module tree will be made available.
do i need this change this ?

make INSTALL_MOD_PATH=../lib/modules/3.4.104+ modules_install
or
make INSTALL_MOD_PATH=../lib/modules/$(KERNALRELEASE) modules_install

/*

*/
Module.symvers is in "/linux-bananapi" theres no "/output" dir there

and change the related mv commands to:

    mv /root/linux-bananapi/lib/modules /lib/modules
    mv /root/linux-bananapi/lib/firmware /lib/firmware
   
Am i on the riGht track?

Thanks to your tut, you sparked my interest of something I was afraid of.
Now I wanna play with kernals some more....Very cool....as is the bpi
Im a 60 yr old paint and bodyman i know cars, automobile "can bus" is the present and future....for now.
I need this can bus.

I wont post anymore  b4 i RTFM


Thanks

Hello.
I don't know what could be wrong.
Maybe stupid question, but:
Did you use "banana pi" board (first version) ?
Did you build on the banana pi board (not on computer) ?
On my board, i have the /output directory.
This is my new version:
  1. root@bananapi:~/linux-bananapi# uname -a
  2. Linux bananapi 3.4.104 #1 SMP PREEMPT Wed Feb 4 16:27:59 CET 2015 armv7l GNU/Linux
Copy the Code
I can priovide you my "Module.symvers"

Try with this one.

Module.zip

140.09 KB, Downloads: 54

no not stupid question (am i on the wrong version? i'd that pro...depends on wifi   )
sata, duall core and canbus made me a buyer

yes version 1

Linux bananapi 3.4.104+ #1 SMP PREEMPT Thu Jan 8 15:40:40 CET 2015 armv7l GNU/Linux
yes built on the banana board

when i origionally ran command
# make uImage modules
the screen appeared to hang and spit out a couple lines of whitespace so i hit enter a couple times then got the command prompt
I'll try your Module symvers.
if not...I am not so far along I cant start with a clean install. I have only added a sata drive since last post.

I just set up debian desktop machine.
normally would that be ok...if i set up the proper environment?
I have openwrt on routers, nslu2, nas200...now its rpi bpi it seems to make sense to cross-compile.

ill post how i make out....
I just cant let go of the can bus issue...I live for the challenge.
thanks





the warning was there i ...how did i overlook it ?...long nights?... wtf

"Linux bananapi 3.4.104" instead of "Linux bananapi 3.4.104+", because i was unable to find same sources than Bananian

I'm sorry I wasted your time.
i should not have jumped the beginners section ...i seen ur tut wanted that canbus

thank you for your help...


Update
Started from scratch. and changed the references "3.4.104" to "3.4.104+"
I had a few errors but overall everything went well.

I changed default speed to 1MHZ ...to match high end of the MCP2551 CAN Transceiver used in the schematics from ELM237 OBD to rs232 interpreter (do not use 1mhz on the J1962 interface...I am testing MCP2551)

running "python pyCan-example.py" yielded
....... swig-python wrapper loaded
....... bit rate changed
... sent message
... sent message
... sent message
... sent message
... sent message
Wait 10 sec for an message.....
appears all went well...The rest needs placed in a different thread or forum if anyone is interested.

A big thank you goes to selqcir for the great work

Is there a possibility that canbus support will be in main bananian branch for default? Or build better package that is installed with oneliner from git or even from apt-get? I can follow the instructions but as mentor for some bpi owners & car enthusiasts I would like that all neccesary things will be in the distro if one will choose bananian as the basis of the project.

Could you please post some pics from pinout in the board and canbus connection to the vehicle?

shAGGie  
to get the right linux.headers (build folder) just
apt-get install linux-headers

so you don't need to change the kernel

best regards

Dear all, C/Q selqcir

I tried to adapt the steps, but for my cubie board 2

First, here is my FEX  modification ...
Base on https://microdotup.wordpress.com/2014/07/04/87/ looks like bananapi it use H20 + H21 as CAN_TX and CAN_RX
  1. [can_para]
  2. can_used = 1
  3. can_tx = port:PH20<4><default><default><default>
  4. can_rx = port:PH21<4><default><default><default>
Copy the Code


after  reboot, I got /dev/can0

But ... dmesg show some error.
