J1939 support: plans for integration? / SocketCAN user forum

[Christoph Appel]

Hello,

are there any plans for a "streamlined" integration of J1939 support
into linux-can i.e. the kernel main line?

Is there a separate SocketCAN user forum?

Thanks in advance!

Christoph

This has always been the target, and still is.
The number of known users is very small, and do not convince linux-can maintainers
yet that the approach of the stack is a good approach.

You're welcome to join this effort.

How do you use the current J1939 stack?
Do you use Transport Protocol, Address Claiming, ....
Do you use it only on developer PC, or on production items.
Mr. Hartkopp & I are very interested in feedback of other users.

Kind regards,
Kurt

I see.

I am in the early process of evaluating possibilities
deploying J1939 in farm machinery (primary
data logging purposes with a couple of bus requests).
So for now, I only use the Linux stack on virtual busses.

The latter is planned, as we try to integrate our bus logging
facilities seamlessly.

> Do you use it only on developer PC, or on production items.
There will be in-house products for research purposes, both
PC-based and embedded.

As we are in early stages, I can't promise anything but will keep you 
informed, if we should finally use the Linux stack.

Kind regards,

If you need some information on the stack's usage, then don't hesitate to ask.

Kind regards,
Kurt

FYI, we (EIA Electronics) have certified a Virtual Terminal
using this j1939 stack. The certification process went
very smooth for the networking tests.

like telnet?

telnet on j1939?

No, I meant the test that are preformed during this isobus certification
on the isobus (J1939) networking level, like dynamic addressing behaviour,
Transport protocol, ...
A beautifull set of nasty corner cases is verified then.
I was a bit curious to the results since I had spent some time on that code.

Being certified at least means that the j1939 stack, together with the userspace programs,
is functionally ready for production.

Isobus (on CAN networking equal to j1939) has become the 'de facto' standard for agriculture
machinery...
