TDA4VM: IPC not bloking QNX issue

Part Number: TDA4VM

Hello:

Hardware: TDA4 evaluation board

SDK-RTO 8.02

SDK-QNX 8.02

I try to implement not blocking reading From IPC Example, I replace timeout in RPMessage_recv( ) with 0. I received leng and detected message from other core, but buffer it's empety, not modified for this function.

Problem is in QNX side.

Any suggest ?
