IM8MQ using ECSPI with DMA in M4 Core.

Hi,

 

I was wondering if there is any example or tutorial to show how to use DMA in M4 core.

I need to transfer 16-bit data of length 16,000 in full duplex (send and receive simultaneously) at 32MHz, for this I think the normal transfer function won't work. So I was wondering if I could use DMA but in ECSPI driver I could only find DMA Init function and also I couldn't find any driver for DMA.

 

Is there any documentation relating to this ??
