Messages from different Heap

Hi,

Can the receiver get messages allocated from different HEAP for a MessageQ? Let's say there are three cores, Core1 (receiver), 2(sender), 3 (sender) and Core2 and Core3 allocate message from HEAP1 and HEAP2, respectively. In this case, can Core1 receive all messages from Core2 and Core3? If not, where is a MessageQ correlated with a specific HEAP?

Best regards,
Ken
