Qoriq P1016 dma from a port device

Question asked by PaulWalker on Aug 20, 2015

Can DMA be used to transfer data via a local bus i/o port (i.e. static, non-incrementing address) to a RAM block (i.e. normal incrementing address block)?

 

The i/o port is 16-bit local bus address, and I want to do 4K byte transfers.

 

I cant see any way to specify the non-incrementing port address behaviour.

 

Regards,

Paul
