Hi Ronny,
OK now I understand better what you are seeing. I was confused by your original post which seemed to say you hit an assertion in the context of Ipc_start(). If the assertion is happening in the context of your own HeapMemMP_create() call, it is probably because you are setting
heapMemMPParams.regionId = 1;
Yet in the .cfg file I only see SharedRegion.setEntryMeta() being called to create SR 0. You need to create SR 1 before you can create a HeapMemMP instance from it.
Best regards,
Vincent
