Part Number: TDA2SX

Dear:

When I migrate algorithm to dsp, I encountered the problem, out of memory when I used malloc()

[HOST] [DSP2 ]     29.764198 s: ### XDC ASSERT - ERROR CALLBACK START ###
[HOST] [DSP2 ]     29.764228 s:
[HOST] [DSP2 ]     29.764259 s: out of memory: handle=0xa3652490, size=1048584
[HOST] [DSP2 ]     29.764289 s:
[HOST] [DSP2 ]     29.764320 s: ### XDC ASSERT - ERROR CALLBACK END ###

Yes, I used vision SDK 3.0.7. Except How to modify heapsize for Dsp,

I also have another question:How to use dsp data section, can you give me an example?

Hi,

Don't use malloc(), calloc() function to allocate memory in vision SDK.

Use the below API for memory allocation in vision SDK

/**
*******************************************************************************
*
* \brief Allocate memory from Frame buffer memory pool
*
* \param heapId [IN] Heap ID
* \param size [IN] size in bytes
* \param align [IN] alignment in bytes
*
* \return NULL or error, else memory pointer
*
*******************************************************************************
*/
Ptr Utils_memAlloc(Utils_HeapId heapId, UInt32 size, UInt32 align)

Thanks

Gaviraju
