Hello,
I'm using the latest RL-ARM (3.50). Occasionally, a RTX task remains hanging (usually that happens after long runs - at least a day) - even a totally innocent looking task. I managed to catch it once with the debugger and it seems that the delay timer of the task is not decremented anymore - however the other tasks run normally. Keil said something about 3.40 having some known deadlocks of RTX - have you noticed these too?I will contact tech. support tomorrow and will report further details if necessary.
