Hello, Could someone please help me out with this issue? This is an important issue for us as it is hindering efficient debugging.
We thought of moving the application to the alchemy skin but given the fact that the posix skin is the fastest ( https://xenomai.org/ pipermail/xenomai/2017-June/037400.html ) we would like to stick with posix.
