spidev DMA

Question asked by Niklas Molin on Apr 23, 2014

Hi.

 

I'm trying to transfer a lot of data via the spi (programming another chip).

I notice that can maximum transfer 255 bytes per transaction (if I try more, it won't transfer anything).

Is it possible to use the DMA to do this via spidev or do I have to write my own "driver" to do that?

 

Thanks,

Niklas
