Need support J1939 protocol support to my kernel (v3.8 on BeagleBone Black)

[Swapnil Patil]

Hi Mike,

Thanks for the reply
I have few question before I start building.

1. Which debain version you are using
    can you share the link from where you have taken reference

2. git merge j1939/v3.6
    do i need to build the kernal after doing the above step

3. can you post your kernal image that you build and share the link
    it will be a great help


Thank You
Swapnil Patil

Need support J1939 protocol support to my kernel (v3.8 on BeagleBone Black)

Hi Kurt,

             Thanks for your reply.
I am using Begalbone Black with Ubuntu 13.04
I am able to transmit the RAW and extended can message over the can
bus using can utility
Now I want to use  J1939 stack.
I downloaded the
Linux-can-can-j1939-modules and Linux-can-iproute2-j1939  and tried to
build them but it failed

Log of iproute2-j1939$ make

make[1]: Entering directory `/home/ubuntu/BBB/iproute2-j1939/misc'
gcc -D_GNU_SOURCE -O2 -Wstrict-prototypes -Wall -I../include
-DRESOLVE_HOSTNAM -DLIBDIR=\"/usr/lib/\" -I  -o arpdarpd.c
../lib/libnetlink.a ../lib/libutil.-ldb -lpthread
gcc: error: arpd: No such file or directory

Log of can-j1939-modules: make
/home/ubuntu/BBB/can-j1939-modules/net/can/j1939/rtnl.c:232:25: error:
âstruct netlink_skb_parmsâ has no member namedâpidâ
/

      If someone already build this on Begalbone black with ubuntu
13.04 or angstrom kernel Please add the steps

Thanks
Swapnil

Hi,

Thanks for your interest in this J1939 module.
Please note taht the mailing list for discussions about this
is linux-can@vger.kernel.org.

I personnaly have not tried anything on a BeagleBoneBlack, but I know
people who have used can-j1939 on this device.
I do not have the details about which system they used: ubuntu, ...

Please find my answers below.

The way you described your situation gives not many details.
Can you give more detail what exactly fails to compile, and how that fails?

I'll describe very high level the steps here:

* kernel
	* grab kernel sources
	* merge can-j1939 git
	* compile kernel
* optionally fix some headers in your cross-compiler
* grab+compile can-utils-j1939
* grab+compile iproute2-j1939

From what I can tell, this is not a compile problem.
This is the ip tool that cannot parse the j1939 command line.

You should use a j1939-enabled iproute2.

Kind regards,
