Hello,

 

I've done searching through the forum on this topic, but the results were from many years ago. 

Does anyone know the procedure of using DMA within the MQX OS with MFS?

 

We will be writing to an SD card and would like to unload the processor as much as possible.  I searched for "DMA" in the MQX RTOS MFS User's Guide rev 2.9 and came back with 0 hits.

 

The processor is in the K64F family.  The processor reference manual has information on DMA and SDHC, but I don't know how to use the DMA portion with MQX when writing to an SD card using MFS.

 

Thanks
