[Xenomai-help] CAN driver

[Xenomai-help] CAN driver

[Roland Tollenaar]

Hi list,

does anyone have, or can anyone direct met to a project or code-snippet 
that shows how the CAN driver in the xenomai patch is used in an 
application? If not that any documentation that gives and explains what 
calls it responds to.

Would help a lot.

Thanks in advance.

Roland

Check src/utils/can/ on some tools that can also serve as nice examples.
But maybe we should also add even simpler demo code to the examples
repository. Just takes someone to write them...

The utility programs rtcanconfig, rtcansend and rtcanrcv in 
src/utils/can already demonstrate most of RT-Socket-CAN's functionality 
including filter definition and error handling. I do not see a need for 
simpler examples. I have attached a patch for a nice program to measure 
the round trip time of CAN messages. It contrast to the other CAN 
utility programs, it uses the POSIX-API and works as-is for Socket-CAN 
as well. Jan, any objections to include it? If yes, I'm going to provide 
a README.

BTW: some time ago I provided a patch to make the CAN utility programs 
part of the Doxygen documentation. IIRC, we said it's nice to have 
hyperlinked examples in general.

Wolfgang.

Yeah, maybe already a link (README) from the examples repos would be
enough to point beginners to them. Or maybe we should ask some beginners
what they expect, what they didn't understand... (Roland?)

On first glance, nope, looks nice and clean.

Some link at hand? Does it still apply? Sounds like something worth to
apply.

Forgot to mention, that there is a README in src/utils/can and 
ksrc/drivers/can.

OK, a revised patch will follow. And shouldn't we have separate sub-dirs 
for each skin in examples/rtdm/profiles/can and serial as well. The 
Makefile is currently valid only for one skin, at least.

See https://mail.gna.org/public/xenomai-core/2006-11/msg00033.html.
My patch was for the CAN utilities only. The idea was to have a more 
general implementation including code snippets and now examples as well.

Re: [Xenomai-help] CAN driver

[Roland Tollenaar]

Hi,

depending on advice on my email on the tsc problem I am having I will 
now try and find out how the user-space side of xenomai is to be used. 
Make a simple structure as a Qt thread (in which I intend to write the 
application) and then dig into the CAN stuff.

So in regard to this:
>> Yeah, maybe already a link (README) from the examples repos would be
>> enough to point beginners to them. Or maybe we should ask some beginners
>> what they expect, what they didn't understand... (Roland?)
I will comment on as soon as I have enough insight in xenomai's typical 
usage. Before then my opinion will probably not be worth much.

Besides we are only now going to order the PEAKCAN dongle so I will only 
be able to test something next week.

Thanks.

Roland.

xeno_can_virt may help to do some testing even without hardware. It
emulates a local virtual CAN bus between 2 or more nodes.

Gilles, as you are planning to regenerate the docs for trunk anyway,
would you merge this patch (or better the corrected version) at that chance?

I compiled doxygen 1.4.6 and generated the documentation with it, but I
do not get the nice tabs at the top of the page, so the next step is to
ask Philippe: where did you get the version of doxygen 1.4.6 that
generates such a nice output ?

Attached is a revised patch for hyper-linking with example and utility 
programs. Apart from the CAN utilities, I have also added cross-link.c 
for RTserial and the code snippets of the native skin by adding 
"@example" tags to the appropriate source files. For the "demos" of the 
skins it was not obvious for me where to put them. The examples are then 
also part of the PDF documentation. Please have a look, hope you like 
it. I personally find the hyper-linking very useful.

Wolfgang.

Ok. I finally got doxygen 1.4.6 tabs (the problem was the filesystem
rights of the tabs.css file), I will include your patch tonight.

Hi, I have included your patch, but there is again some doxygen magic
that I do not understand, there are only a few links to the examples in
the documented files. For example in native condition variables
documentation page, there is no link to the cond.c example, but the
example is included (whereas examples sources that are not mentioned in
the source are not included at all). Any idea what could be the cause ?

Re: [Xenomai-help] CAN driver

[roland Tollenaar]

Hi,

The first thing I notice is that I do not seem to find the devices
rtcan0, rtcan1 etc.

They are mentioned in the documentation and I presume they must be nodes in
/dev or so. But I cannot find them. rt-can is statically built into my
kernel so I don;t need to load any modules. I have selected the SJA
chip and the PEAK CAN Dongle.

I am reading the README in /src/can and the one in ksrc/drivers/can.

/proc/rtcan is present but no devices rtcan0, rtcan1 etc under it.

What have I missed?

Regards,

Roland

Re: [Xenomai-help] CAN driver

[roland Tollenaar]

Hi,

hope I'm not overloading the list. :)

The second thing I notice is that the code in the /src/utils/can
applications very low level. Admirable to be sure but for lesser
programming fundi's such as myself higher
level calls are more useful. What I was kind of hoping for was the typical

can_init(fd)
can_write(fd,can_mesg)
can_read(...
etc

API calls.

do they exist? If yes how can I incorporate them in my program?

Continuing my browsing......

Regards,

Roland

Nope, RT-CAN is incorporating the latest shiny Socket-CAN model which
is, well, socket-based. It's not the n-th specific, incompatible CAN
character device implementation.

rtcanX are networking devices, but only visible in the context of
RTDM/AF_CAN. To enable them, use rtcanconfig as explained in the README.

Hi Jan,

What is this?

 To enable them, use rtcanconfig as explained in the README.
Which README are you referring to? The only one I know of that says
something about rtcanconfig is in /src/utils/can and it does not
explain how to use ctrlmode and bittime. There is an example in it

rtcanconfig rtcan0 --baudrate=125000 start.

If I try

rtcanconfig rtcan0 --baudrate=125000 start

I get:

"Can't get interface index for rtcan0, code=-19"

Any idea what is wrong?

Your devices have not yet show up on your system. I guess there is no 
entry in /proc/rtcan/devices. Check your boot log.

There are no entries in /prc/rtcan/deices.

dmesg | grep "rtcan" or
dmesg | grep "rtcan*"

yields nothing.

I have checked the .config for the kernel build and CAN is statically
built into it.

I would prefer to statically build these things into the kernel due to
unwieldiness of my ditribution. If this is not possible I will make
modules. But is this the cause of problem I am having?

I have no device hooked to my system (PEAK dongle on its way) and the
virtual driver and TX loopback ability  has been excluded from the
kernel build. Is this possibly why i have no devices listed in
proc/rtcan/devices?

Can you post the compete dmesg output?

The driver for the dongle will not start properly when statically linked 
into the kernel. There should be a log message, though.

Without device it will not register anyhow and see above.

Hi,

I have now built the kernel with the virtual driver statically built
into it. No difference still no devices.

No log message unless I am missing something. What is the module
called? After the
make modules in the kernel building process I will have to find it and
store it somewhere I will try loading it manually when the new kernel
is booted.

The virtual driver I can build in statically?

 It is attached as a txt file. The errors regarding ehci, ohci, uhci
and mass_storage are results of trying to load modules that I have
statically built into the kernel.

[roland Tollenaar]

Xenomai itself must be running because the the programs in the

Output of "dmesg" please or the log of your console output. You should 
find lines similar to the following:

I-pipe: Domain Xenomai registered.
Xenomai: hal/powerpc started.
Xenomai: real-time nucleus v2.4-devel (Bells Of Lal) loaded.
Xenomai: starting native API services.
Xenomai: starting POSIX services.
Xenomai: starting RTDM services.

I did this

#/var> grep -r "Xenomai" ./  >> dmesg.txt

I found what you are looking for you will find it in the message attached.

I did the same for rtcan which should yield the last 4 lines

and found this:

./log/syslog:Feb 22 13:21:38 (none) kernel: rtcan: registered rtcan0
./log/syslog:Feb 22 13:21:38 (none) kernel: rtcan0: VIRT driver loaded
./log/syslog:Feb 22 13:21:38 (none) kernel: rtcan: registered rtcan1

./adm/dmesg:rtcan: registered rtcan0

Hope this helps us?

Re: [Xenomai-help] CAN driver

[roland Tollenaar]

Hi,

This is a bit better.

/proc/rtcan/rtcan0/info


Device     rtcan0
Controller <virtual>
Board      <virtual>
Clock-Hz   0
Baudrate   undefined
Bit-time   brp=0 prop_seg=0 phase_seg1=0 phase_seg2=0 sjw=0 sam=0
Ctrl-Mode
State      stopped
TX-Counter 0
RX-Counter 0
Errors     0
Refcount   0

for rtcan1

Device     rtcan1
Controller <virtual>
Board      <virtual>
Clock-Hz   0
Baudrate   undefined
Bit-time   brp=0 prop_seg=0 phase_seg1=0 phase_seg2=0 sjw=0 sam=0
Ctrl-Mode
State      stopped
TX-Counter 0
RX-Counter 0
Errors     0
Refcount   0


And after ./rtcanconfig rtcan0 --baudrate=500000 start

Device     rtcan0
Controller <virtual>
Board      <virtual>
Clock-Hz   0
Baudrate   undefined
Bit-time   brp=0 prop_seg=0 phase_seg1=0 phase_seg2=0 sjw=0 sam=0
Ctrl-Mode
State      active
TX-Counter 0
RX-Counter 0
Errors     0
Refcount   0

Why is the Baudrate undefined? I thought rtconfig should set this to 500000 ?

Is this all fine now? I oculd have sworn that I checked proc/rtcan
after I had recompiled the kernel with the virtual driver.

Anyhow. Is there a small program that I can compile to test the
virtual can with? I presume i can send it messages with rtcansend and
read the messages with rtcanrecieve?

I still have the outstanding question of what the module will be
called for the PEAK CAN dongle. I have to find it after make modules
to squirrle it away so i can load it after booting due to the
complications with my live distribution.  You said that I cannot build
that into the kernel statically correct? Can it be loaded without the
actual device being connected?

Maybe a small suggestion. Would it not be better to have the virtual
can driver built into the kernel by default. As a new user I did not
select it, saw no reason to.


Thanks.

Roland.

And /proc/rtcan/devices is also useful.

Because it's a virtual devices just routing the messages to the other
virtual devices.

Looks good.

I said, it can be statically linked into the kernel but it will not work 
(without modification, we can discuss this issue when you have a PCAN 
dongle). What should a driver without hardware be good for?

Might be useful, indeed. BTW: there is a help available for each 
configuration option?

Re: [Xenomai-help] CAN driver

Hi Wolfgang,

Device rtcan0 Baudrate undefined State active TXCounter 7 RXCounter 5 Errors 0
Device rtcan1 Baudrate undefined State stopped TXCounter 0 RXCounter 0 Errors 0

Works. Can send and recieve messages on it. Interesting may be this:
If i send with rtcansend then in another console recieve the messages
will not display. I would have expected the messages to be in the
stack and display (depending how many messages the stack can hold).
Why is that expectation incorrect?

Good question. On the other hand it would be useful to know which
module I have to
pick out and load. Then I can compile the kernel for that so long and
make a structure that loads it after booting. But that can be done
later too.

There should be. I think I used the help. Will check again for you
when I change the configuration to load the PEAK driver as a module.

There is no per device stack. The messages will be delivered directly to 
  the sockets receive buffer if it is listening and the filter does match.

You can do it now, just try and then ask questions.

Did it now, now there are questions. :)

The README says something about loading modules only it talks about

insmod xeno_can.o
and some others I cannot recall now (on windows now haven't got linux 
handy).

If I do the make modules and make modules_install I end up with a 
rtcan_peak_dngl.ko (again only the extension is accurate). modprobing 
that does not work so I insmod it. I get a message that invalid 
parameters were supplied or somethign like that.

In a flash I did see something mentioned about loading the modules with 
parameters (maybe you mentioned it?) but I cannot find the documentation 
that says something about this. Where must I look?

Regards,

Roland.

Well, the modules name is xeno_can_peak_dng.ko as listed when doing:

   $ make modules
   ...
   LD [M]  drivers/xenomai/can/sja1000/xeno_can_peak_dng.ko
                                       ^^^^^^^^^^^^^^^^^^^^

And I load the modules with the following command:

   $ modprobe xeno_can_peak_dng type=epp io=0x378 irq=7

Yes I have this.

I am having trouble here. The above line returns:
FATAL Module xeno_can_peak_dng not found

even when I call it from the directory the driver is in.

insmod from the directory I have the driver in returns:

insmod: error inserting 'xeno_can_peak_dng.ko': -1 no such device.

Any idea what may be wrong?

Roland

Hi

Just a quick update on the situation.

I had to sort out the module.conf matter but this now also responds with:

"No such device"

Which I presume is correct if the device is not attached?

What would be nice is a brief explantion of the paramters

io=0x378 looks like the hardware address of the parallel port. ?
irq the interrupt request number. Why 7? Is that specific to the
parallel port or would that be the same for all the CAN devices?
type=epp ? What does this mean?

Regards,

Roland.

Maybe running modinfo xeno_can_peak_dng would help ?

This is the output. This is probably a beginners question but why irq

info.

Any idea?

This link should help to answer most of your parallel port questions: 
http://www.beyondlogic.org/epp/epp.htm

And for kernel calls to control the parallel port, see: 
http://people.redhat.com/twaugh/parport/html/parportguide.html - The 
information is relevant to vintage 2.2.x as well as for the latest 2.6.xx 
kernels.

hi Paul,

Thanks for the urls. They are very helpful.

Does anyone know what the future of the parallel port is going to be?
Will it be disappearing from the PC,s in the near future or will it
still be around on new machines for a while?

Already vanished from laptops, will probably disappear from commodity
desktop hardware in the next years as well. But I guess industrial
boards will stick to it a bit longer.

USB has reached up, at least for lab scenarios (and your CAN dongle it
surely intended for such a use case). RT and USB is still an engineering
task to be finished. First approaches are there for Xenomai, but they
need stabilisation and interface standardisation.

How long is the development of RT-USB-CAN expected to take still.
Months or years?

Until our pain with current special PC104 RS-422 cards gets too huge and
we start working on USB dongle integration again - or someone considers
an RT-USB stack worth to work on or to sponsor. There is no automatism
when relying on pure "open source magic".

I think you'll find many commodity manufacturers already label the parallel 
port as "legacy".. In fact, a number of laptops are shipped without one!

 I don't think we will see the parallel port disappear for a few years, but 
the time will come - The alternatives are PCI cards (worth fitting one if 
only to take advantage of the faster IO read/writes), or using one of the low 
cost fpga cards with custom firmware. It has been muted in some quarters that 
the PCI bus will also disappear, so the fpga option may not sound as daft as 
it might first appear.

I do believe that PEAK USB CAN adapters come optically isolated for just
this reason. I know because its and option and more expensive than the
ones we purchased. At that stage we were only using them for testing bus's.

Besides firewire (1394 was it not?) what else are the options? Become
vendor driven things, ProfiBus, Devicenet (variant of CAN), anything else?

By the way, what is CANOpen going to do long term. Stick around or is it
already being driven out by other protocols?

The devices will be available when after the driver have properly 
loaded. You can find corresponding messages in the system log (type 
dmesg to list them. Here is the output from my Laptop:

RT-Socket-CAN 0.20.2 - (C) 2006 RT-Socket-CAN Development Team
rtcan: registered rtcan0
rtcan0: VIRT driver loaded
rtcan: registered rtcan1
rtcan1: VIRT driver loaded

You must build the driver for the PEAK CAN Dongle as module and specify
the port type, I/O port and IRQ number when you load it. But as Jan 
already pointed out, you can use the virtual CAN driver for getting started.

What have you selected? Check your boot log!
