It would be awesome to have a DMA module that is incorporated into the RTOS (uses the signals and interrupt locks for an easy to use module) to use with the file system and any large data transfer.

Hi James, 

Thanks for the feedback! 

A few questions to be sure I understand. I assume you're focusing on data moving through the file system on the MCU? And you're using the FatFs for the file system code? Also, when you say 'large data transfer', where is the data's destination? Storage media such as flash or USB etc?

Best Regards,

Tyler

Hey Tyler,


Yes, what you stated above is correct, but in addition to that I would be using it for in/out of the AES engine, in/out to SDRAM, in/out to QSPI, and in/out to external NOR static flash.  Something similar to how LPC Open works, but easier to use and integrated into your RTOS would be awesome.


Thanks, let me know if you have any more questions.
