Subject: [Xenomai] Strange behaviour after calling clock_settime
Date: Wed, 14 Mar 2018 11:42:58 +0100 [thread overview]
Message-ID: <1521024178.8992.7.camel@sprinte.eu> (raw)
Hi,
The current xenomai documentation states that it is allowed to call
clock_settime with CLOCK_REALTIME parameter to set the value of the
xenomai realtime clock. On our board, the value at bootup is always 0
(so, epoch), despite the hardware clock being correctly set.
However, we experience bad behaviour when doing so. Notably, alchemy
condition variables seems to no longer work. Resetting the xenomai
CLOCK_REALTIME to the initial value puts things back in order.
Is it a known issue ? Are we doing something wrong ? Or is it just
better to let the xenomai CLOCK_REALTIME live its life, considering it
as a CLOCK_MONOTONIC, and rely to CLOCK_HOST_REALTIME whenever we need
real dates ?
Regards
Julien
