Hi Everyone

I've been working with MQX starting with version 3.7 and now have downloaded the latest 4.0 version.

In MQX 3.8 SPI drivers were DMA based, however when i have checked the code for in MQX 4.0 i noticed that there is no DMA support for SPI drivers anymore.

This is not a concern, per say, however, i just would like to know if there was a specific reason for removing DMA support form the SPI drivers.

Was it done because of some known issues with DMA/SPI combination or for some other reason?

The reason im asking is because i would like to use DMA based SPI transfers in our project.

Thank you
