Hi,
I have modified one LPCOpen dual core examples, "dc_sa_blinky" for M4 and "dc_sa_blinky_m0" for M0. I have added an LCD refresh task. so, when a message is received from the other core, in addition to LED blink task, the LCD refresh task is also done.
M4 sends message every 5 sec to M0, and M0 sends message every 10 sec to M4.

the application seems to work fine at first, but after some minutes, about 15 minutes, it hangs!!

What actually debugging have you already done to try to identify the cause of the problem?

Maybe you have run out of heap or stack space?
