Interesting. OK. We don't have much support here for that board. I don't know anyone that has one. I have seen maybe 2 questions over the years on this board. I guess we can wait and see if anyone has feedback for you on this.

You need to write a kernel module or device driver if you want to use SPI with DMA. You don’t have to do anything special to use DMA because the SPI driver is written to use DMA when the size of the transfer exceeds a certain threshold.
