Hi,
Ok rtcan2 and the peak dongle seem to be working. I am now running
into new problems with my application.
The first question is how do I reset the ctrl_mode to nothing.
Listen-only and loopback are both debugging/testing states but how do
I reset them to ....what is the normal state called? At the moment I
am in loop_back mode all the time.
# rtcanconfig -c none rtcan0
Wiil be documented a.s.a.p.
I am writing to rtcan2 from my application and subsequently reading
from it. Works by the look of things BUT my CPU is working overtime.
syslogd and klogd are consuming 50-60% plus 30-40% of the processor
O, ah, what gets logged that often?
time. Obviously everything gets sticky but I can still see that the
task times are being maintained and the actual applicaiton is using
less than 3% of the processor time.
Polling too often is a typical problem of the polling method.
Besides this simple can functionality there is nothing happening in
the tasks and this does not happen if I write and read on rtcan0.
Finally after a long while of running and stopping the application I
get the message
rt_dev_bind: -no space left on device.
This bind is called before the read-call.
Can anyone please shed some light on these issues. Much appreciated as
usual.
Grrr, I already told you that it does not make sense to use bind and
ioctl SSIOCGIFINDEX for every read here:

(re-)read
http://www.xenomai.org/documentation/trunk/html/api/group__rtcan.html#Bind
and
http://www.xenomai.org/documentation/trunk/html/api/group__rtcan.html#gee74ae50c8ea0a6aee277c6f124a3866
to understand why.
Nevertheless, there seem to be a memory leak when re-binding the device.
I will have a look a.s.a.p. (but it should not be a problem for your app
when you just do it once per socket).
Wolfgang.
Kind regards,
Roland
