Memory allocation on TMS570LS31HDK

Hi All,

I am doing malloc()  for a size of 5 Kilo Bytes. I am unable to allocate memory with this size. Maximum I am able to allocate for a size of 1 Kilo Bytes.

Is there any memory limitation on the board?

For my program, I require 300 Kilo Bytes of Heap memory. Code and data sizes will be around 900 Kilo Bytes. Is it possible to do this on this board?

I require bare minimum functionality on the board. I have program in the following manner.

main()

{

     // memory allocations

    // Instantiating the handle

    // File inputs and outputs (PCM)

    // Processing the data in a loop

    // Freeing the memory allocations

}

}
