[-- Attachment #1: Type: text/plain, Size: 1158 bytes --]

i want to revive the topic over the problem RTSER_RTIOC_WAIT_EVENT
while compiling cross-link.c program. I cann't resolve my problem
after doing some solution given by the others

Loading module:

insmod ./xeno_16550A.ko io=0x3f8,0x2f8 irq=4,3 tx_fifo=10,20
start_index=0 (i have two serial ports on my pc)

running crosslink test:

main : write-file opened
main : write-config written
main : read-file opened
main : read-config written
main : write-task created
main : read-task created
main : starting write-task
main : starting read-task
 Nr |   write->irq    |    irq->read    |   write->read   |
-----------------------------------------------------------
read_task: error on RTSER_RTIOC_WAIT_EVENT, Connection timed out
read_task: error on RTSER_RTIOC_WAIT_EVENT, Connection timed out

...



running test:

cat /proc/xenomai/irq

IRQ         CPU0
  3:        1089         rtser1
  4:        5155         rtser0
33033:           0         [IPI0]
33036:     1484080         [timer]
33037:           0         [critical sync]
33090:    11882308         [virtual]

the values increased with time.


thanks,


configuration :  linux 2.6.38 and xenomai 2.6

Hm, is a FIFO size of 20 supported by the hardware? For a first try I
would drop "tx_fifo=10,20" (using the default of 16 for both uarts).

You get interrupts, at least, but not the same amount, strange. What
cross-link command options do you use?

Hm, what does rt_dev_ioctl() return?

Well, the ioctl waits for certain events and informs the task when they
occur. "cross_link.c" actually waits for the RTSER_EVENT_RXPEND meaning
that RX data are available. So, the sub-sequent read will/must work. You
do not need to call that ioctl but the read directly. But I doubt that
the read return successfully.

Maybe the interrupt service routine does detect errors due to hardware
problems:

http://www.rts.uni-hannover.de/xenomai/lxr/source/ksrc/drivers/serial/16550A.c#213

and that's why the interrupt counter increases.

You could check that by setting RTSER_EVENT_ERRPEND or reading the
status using the ioctl request RTSER_RTIOC_GET_STATUS.

[-- Attachment #1: Type: text/plain, Size: 3978 bytes --]

hi,

with option RTSER_RTIOC_WAIT_EVENT in rt_dev_ioctl(), this function returns
un number -110 (Connection timed out)
with option RTSER_RTIOC_GET_STATUS in rt_dev_ioctl(), this function returns
un number 0 (not message)

Anyway, currently it works without  rt_dev_ioctl(), i can see rt_dev_read()
wait data event (with debug mode) while giving the period of write
task,  for exemple  = two seconds.

so can i remove the funtion rt_dev_ioctl?

You should call this function *after* the timeout happened. What does
the "struct rtser_status"  contain? Especially the "line_status" is of
interest.

The rt_dev_ioctl should work. You can remove it, but the problem will
remain. To debug the problem you could also add some printk's here:

http://www.rts.uni-hannover.de/xenomai/lxr/source/ksrc/drivers/serial/16550A.c#223

Especially the value of "iir" might be interesting.

hello,

i don't know how call the function rt_dev_ioctl() after the timeout
happened, this function is called in the begining of "while" loop
(cross-link program).
I get the value of struct  rtser_status,
line status = 96
modem status = 176
to be honest, i don't know why cross-line program works without the
function  rt_dev_ioctl() with  RTSER_RTIOC_WAIT_EVENT in  option.

main : write-file opened
main : write-config written
main : read-file opened

i tried to send a character table, and it also worked.

Hm, maybe you receive something, but the numbers are bogous. To
understand better what's going on, coud you please apply the attached
patch to your Xenomai tree, rebuild the kernel and send the dmesg output
while running cross-link.

BTW: what Xenomai version are you using?

Wolfgang.

... and so on.

This looks completely normal and I'm really puzzled why the
rt_dev_ioctl(RTSER_RTIOC_WAIT_EVENT) does not work as expected. Ah, I
just realized that the following patch was not yet applied:

https://mail.gna.org/public/xenomai-core/2011-11/msg00009.html

I think it will fix your problem.

Yes. At a closer look I realized that cross-link.c does set it's own
configuration. Therefore I have a few questions:

- do you use an *unmodified* version of cross-link.c?

- What Xenomai version do you use?

- What Linux kernel version do you use?

- How do you build "cross-link"?

And please do not drop the CC to the list.

Sorry, it looks like I completely forgot this patch. Could you rebase it
on the current contents of xenomai-2.6 so that I can merge it?

Actually, the patches are merged in xenomai-2.6 repository. The problem
we have is simply that xenomai 2.6.0 is too old.

Argh, you are right. Sorry for the noise.

Re: [Xenomai-help] Cross-link.c ---RTSER_RTIOC_WAIT_EVENT

[Minh GIANG]

[-- Attachment #1: Type: text/plain, Size: 3573 bytes --]

ok for CC, i was afraid of spam everyone by my mail. I answer your
questions.

- non, i didn't modify cross-link program  (even if i used to modify this
program to make it run, but it worked the same way)

- Xenomai 2.6

- Linux 2.6.38 and patch Adeos 2.6.38 of course

- i build the program in Eclipse C++ so my command in setting configuration
is

command :   g++
All options:   -l/usr/xenomai/include -O3 -wall -c -fmessage-length=0

Well, i will soon rebuild my kernel with this patch

Goodbye

oh, it seems to work perfectly, i don't know why it works in this case when

program don't compile in Eclipse), is

static const struct rtser_config read_config = {

static const struct rtser_config write_config = {
RTSER_SET_BAUD | RTSER_SET_TIMESTAMP_HISTORY,
115200,
RTSER_DEF_TIMESTAMP_HISTORY,
/* the rest implicitely remains default */
};

maybe, i don't compile with good parameters in Eclipse?
my version Xenomai 2.6.0

That's how the program should be comiled and linked.

Yes, that's your problem. And exactly to avoid such problems, Xenomai
provides the script "xeno-config" to retrieve proper compiler and linker
options.

I also recommend to update to a more recent version.

hello,

Thank you for helping me solve my problem.

You recommend me to update to a more recent version. But I think the
xenomai version 2.6.0 is the lastest version over http://www.xenomai.org
 site.

By the way, i have a short question. When i make run cross-link program, i
don't understand why there is a leak memory. Even if, i try to remove all
parasite in while loop, but the leak memory is always constant. i think the
problem comes from rt_dev_write() or rt_dev_read() which don't release the
memory buffer. im wrong?

You are right. The latest fixes are in the git repository, which you can
get with the following command:

  $ git clone git://git.xenomai.org/xenomai-2.6.git

What makes you think that there is a memory leak? How do you observe it
and what is running while your are testing with cross-link?

Wolfgang.
