Recently, I have been exploring hardware platforms for validation. For morello board, I am trying to build a driver that copies a lot memory from some IO dev [ maybe USB ] to mem [DRAM]. I am trying to do this while the CPU is busy in executing some other code. So, I looked for a DMA controller in the Morello TRM memory map layouts. But I cannot find any address for DMA controller. Is there an DMA controller on morello board ? If not the case what else can I do ?
