Why Message_open also output invalid QueueId?

rengang hou

I am running two tasks on Core0 and Core1. Task one on Core0 creates one MessageQ to receive message from other Cores。I create another MessageQ on Core1 ,but whenever from Core0 or Core1, Message_open always outputs invalid queueId(65536), so Task on Core1 can't receive message from other Cores. Please help me, thanks.

Hi Rengang:

65536 is same as 0x1 0000. This is a valid QueueID, and corresponds to a procId of 1 (possibly CORE1, depending on the MultiProc configuraiton), and a QueueIndex of 0 (used internally by MessageQ to index into an array of messageQ objects). QueueID == (procId << 16) | QueueIndex.

Can you give some details on what IPC version you're using, what platform, the CFG file and sample code?

You may also want to check IPC user guide to ensure usage of MessageQ APIs is correct:

Are you passing in the same MessageQ name into MessageQ_open() as what was passed into MessageQ_create() on CORE1?

Hi,

I suggest that you open a new thread, as this one is already marked as answered and it won't gain many attention.

The other problem maybe was the names used like GAnthony said, the id was right. What's exactly your problem?
