Inspect /proc/rtcan or watch the log messages.


Then I presume I will send a message on 1 and then see it appear on 
the rtcanrecv rtcan1 ?


Yes, but with rtcan2.

Does this not depend on the outcome of the earlier inspection of 
/proc/rtcan or is rtcan2 an educated guess? To clarify: I will be 
sending and recieving on rtcan2 in loopback mode in order to test?



The virtual can driver will install two devices. Have you seen something 
different? If you then load xeno_can_peak_dng... The devices will be 
named according to order they are installation, of course.







If things are a bit slow on my side its because I am rushing around 
doing other mandatory things. Only reason I am busy with this as well 
at the moment is because I don;t want to lose the opportunity of 
having you all at your desks :)



While I think about it. How DO I apply your patch. I mean besides using 
the patch tool, which installation steps must I repeat?

1-patch your file
2-run patch_kernel again
3-rebuild the kernel
4-rebuild the modules (make modules)
5-Install modules
(or can I skip 3 and only do 4 and 5?)



1+4+5, nevertheless, I'm going to check-in a revised version of the 
patch later today. Then please do a "svn update" in your Xenomai repository.

Good, because I will be on holiday next week ;-).


That is not good. You sure you don;t want to postpone for a week? :)

Thanks, "ich melde mich" soon. :)

Hi,

My situation is slightly different. The modules don;t get loaded for
some or other reason (not sure why because I do have parport support
<M> selected in the kernel config.

My BIOS settings said ECP instead of EPP ( I still don;t know the

difference) I set it to EPP and the driver seems to load with 
modprobe

now.

Interestingly enough before I changed the BIOS I did try

modprobe xeno_can_peak_dng type=ecp io=0x378 irq=7

but it tells me that ecp is an invalid argument? Why is that?


Kind regards,

Roland
