Hi all, as Olivier told you, I come back to the TSP world. So the "freezing" problem with bb_simu+tsp_bb_provider+tsp_stdout_client is a deadlock in BB.I had the same problem when I tried to make TSP works with vxworks.It appears,when the BB is shadowed, that we don't release the semaphore,so I add the same with the lock operation (don't take semapahore for a shadowed BB).
As fred said, it's weird noobody notice that before, I don't see why. I post a bug in the tracker : #26250.
