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 ??

Hi Sivaram

some examples can be found in SDK_2.6.0_EVK-MIMX8MM (I am not aware of

examples for i.MX8MQ), SDK can be obtained from https://mcuxpresso.nxp.com/en/select 

Best regards

Hi Igor,

The driver for SDMA seems to be missing in IMX8MQ :smileysad:..Can we expect support for SDMA on IMX8MQ  anytime soon..?

Thanks and Regards,
