TMS570LC4357: 64Bit access size to TMS L2RAMW

Hello,

I want to access L2RAMW area with R/W 64-bit access size.

I propose to write the following code :

uint64 READ_64BIT_DATA(uint64* startAddr)

{

            uint64 READ_VALUE;

READ_VALUE = (uint64)(*startAddr);

    return(READ_VALUE);

}

 Is that the good way to access in 64-bit size to the memory ? How to be sure that this code will not generate a 2x32-bit access to memory ?

 Thanks for your answer.

François
