Memory allocation using Eclypse Z7 board issue

[MrLearner]

Hello, I have an issue trying to run the Zmod DAC 1411 demo program on the Ecylpse Z7 board. When we run it, we get an error stating that the buffer cannot be allocated. 

One of the issues we are having seems to be with this portion of the code:

uint32_t* ZMODDAC1411::allocChannelsBuffer(size_t &length) {

    if(length > ZmodDAC1411_MAX_BUFFER_LEN)

    {

    length = ZmodDAC1411_MAX_BUFFER_LEN;

    }

    return (uint32_t *)ZMOD::allocDMABuffer(length * sizeof(uint32_t));

}

Could anyone help us resolve this problem?
