Re: [Emc-developers] [RTAI] rtapi_get_time() returns a constant
Hi all, I finally found the root cause of my problem: it was rtapi_print_msg() which printed a constant (why I don't know, but I guess it is due to the "%lld" format). Using a simple printk in my code for debug and all goes well. Sorry for this false issue.

I did some more experiments: I created a RTAI module (with no LinuxCNC code). This module only does: * Create a RTAI task, call rt_get_real_time_ns() and log this time This way I can see the time changing. It means RTAI setup is fine and my issue is with LCNC HAL or the LCNC HAL module I use (LCEC). I will try to create a simple RT HAL module with the same feature as above and so determine where the issue is located.

Re: [Emc-developers] [RTAI] rtapi_get_time() returns a constant, Ethercat mor generally
I know there in scilab called ethercos and even though used for other purposes there might be useful information. My myself are on the path with soem/soes but currently working with hardware since I discovered drawbacks with the first chip i tried.

Did you have any hints on how to > fix it ? I tried to use rt a while ago but have not yet get rtnet up and running. I have however tried soem Ethercat master and soes Ethercat slave and they work. I run soem Ethercat master within linuxcnc. I should solder and try another board before I continue with the hardware for the Ethercat board. I discovered then using ordinary rt kernel that scheduling is good enough but then logging times of messages sent with Wireshark there sometimes is a delay of up to 5-10 milli seconds. You got rtai and rtnet up and running? > Many thanks for your help No help right now, only new questions.

[Emc-developers] [RTAI] rtapi_get_time() returns a constant
Hi all, I'm J-P working for the REDS institute (Reconfigurable & Embedded Digital Systems) from the HEIG-VD (School of Management and Engineering Vaud), Switzerland. I started a project with LinuxCNC. As initial ramp-up with the src code, I try to integrate the support for Beckhoff EL2252 digital outputs (EtherCAT module, using LCEC HAL module). After some experiments, I found that RTAPI (rtapi_get_time) or RTAI (rt_get_time() timer related functions are not working on my setup: they return a constant value. I checked if the RT Timer was started (using RTAPI and RTAI functions), all seems OK. Most probably, the configuration of the used HW timer is not correct. Didi you already have this kind of issue ? Did you have any hints on how to fix it ? Setup: * LinuxCNC 2.7.13 install from the live CD * machine: Linux A23PC05-linuxCNC 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 GNU/Linux Many thanks for your help J-P -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
