Hi Bari, hi Nicklas
Many thanks for your help/proposals. 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.
