TDA4VM-Q1: C7x Memory tivxAlgiVisionAllocMem Failed

Dear Expert.

I am running a deep learning demo on VM board. When I manually start the application, the following error log repeatedly occurs:

 

Mar 12 19:52:54 app7.info : [C7x_1 ] 2233.820240 s: VX_ZONE_ERROR:[tivxAlgiVisionCreate:358] tivxAlgiVisionAllocMem Failed*

Mar 12 19:52:54 app7.info : [C7x_1 ] 2233.820268 s: VX_ZONE_ERROR:[tivxKernelTIDLCreate:720] tivxAlgiVisionCreate returned NULL*

Before the errors, heap allocation is functioning normally.：

Mar 12 19:15:48 app7.info : [C7x_1 ] 2.396479 s: MEM: Init ... !!!*

Mar 12 19:15:48 app7.info : [C7x_1 ] 2.396490 s: MEM: Created heap (DDR_LOCAL_MEM, id=0, flags=0x00000004) @ 117000000 of size 314572800 bytes !!!*

Any suggestions or experiences you can share would be greatly appreciated.

thanks a lot!

    Hi,

    This seems to that the region is out of memory. Could you please check the memory requirement of your model and increase the C7x memory region accordingly?
