TDA4VM: tivxMemAlloc limitation on R5F

Genius 13655 points

Part Number: TDA4VM

Hello Champs,

Customer is running tivxMemAlloc(size,TIVX_MEM_EXTERNAL) on R5F (MCU2_1) to allocate memory. 

But it fails when the size exceeds 16*1024*1024, it can allocate memory if the size is 4*1024*1024.

Besides, he can allocate 16M memory on DSP core. 

So is there some limitation on R5F core when using tivxMemAlloc?


Thanks
Regards,
Shine
