Hi,
No worries, I've already extracted out the RTDM code and config from the devel
branch and made a patch to import it into the stable branch. (Would you like
the patch file?)
Yes,
I've been having a look at the RTDM code. There's a couple of issues that I'll
be looking at fixing / changing. Let me know if you're interested in any of
them.
1) There's a few minor spelling issues:
EC_RTDM_DOMAIN_QUEQUE EC_RTDM_DOMAIN_QUEUE
EC_RTDM_MASTER_SYNC_MONITOR_QUEQUE EC_RTDM_MASTER_SYNC_MONITOR_QUEUE
ecrt_rtdm_domain_queque ecrt_rtdm_domain_queue
ecrt_rtdm_master_sync_monitor_queque ecrt_rtdm_master_sync_monitor_queue
Feel free to fix it
2) Please correct me if I'm wrong: the RTDM interface only allows for one
domain per master. There are by default up to 5 RTDM devices available but I
would expect the intention for these are to allow different masters rather than
multiple domains for one master.
Yes you are correct. Feel free to fix it. We only integrate a patch, we
are not using the RTDM interface until now.
I was planning on changing the struct CstructMstrAttach to take more than one
domain (with dynamic size) and the domain related functions to take an index as
to which domain you want to call the function for.
Would be great
3) There's possibly some sdo related methods that I will add to the RTDM
interface, but I haven't quite decided yet.
I talked to Florian about this. You need not do sdo configuration during
realtime, you can do it before stepping into realtime with the normal
blocking functions, or you can doit in a seperate thread. So you need
not implement an RTDM interface for this.
Do you use RTAI or Xenomai? I noticed some problems with RTAI, but I
have no time for further testing.
Please note, if you do some work, please focus on the stable tree,
because there are some unstable features in the defel branch.
Best regards
Andreas
Regards,
Graeme.
(PS I'm using RTAI, so I didn't extract the Xenomai stuff for my RTDM patch.
If you would like my patch I can add that in pretty quickly.)

Hello,
We know this,
If you want to build up a productive system you should use the stable
branch. There are some new features in the devel branch which are not
stable until now.
I will talk to Florian about porting the RTDM interface into the stable
branch.
Do you want to use it under RTAI or Xenomai?
Best regards
Andreas

Hi,
Can you please let me know the current status of the repository? I'm
wanting to use the RTDM interface but I notice that the devel branch
(2117) is now quite different to the stable 1.5 branch (2124).
One bug fix in particular for the devel branch (though it may just be
waiting for a merge) is:
diff -ru etherlabmaster-1.5-2117/master/master.c
etherlabmaster-1.5-2117-patch/master/master.c
--- etherlabmaster-1.5-2117/master/master.c 2011-09-17

+++ etherlabmaster-1.5-2117-patch/master/master.c 2011-10-26
11:42:09.000000000 +1300
@@ -161,6 +161,7 @@
master->has_app_time = 0;
master->scan_busy = 0;
+ master->allow_scan = 1;
ec_mutex_init(&master->scan_mutex);
init_waitqueue_head(&master->scan_queue);
I also notice the devel branch hasn't got the bug fix for revision 2120
(Fixed missing return causing slaves not going to OP).
Once I start my app my PC freezes. I haven't started looking into that
one yet.
Is the devel branch generally stable enough to use at the moment?
Thanks,
Graeme.
