External SPI-Flash

Question

Hi everyone, 
 I am using right now external flash(mx25l25645g) through device tree provided by nrf connect SDK. its working fine. 
 I wants to know weather it is using DMA functionality or not. if not how can I leverage DMA in Nordic nRF52840 devices.

Hello 
 In the nRF Connect SDK there are two SPI master drivers that are compatible with nRF52 devices: 
 SPIM , which uses EasyDMA 
 SPI , which does not use EasyDMA 
 So if you want to use DMA, simply make sure you are using the SPIM driver. 
 Best regards,
