i'm a application developer and have some questions about the mxs-auart under Linux 2.6.35 (Freescale BSP) and the iMX28 platform:
Where do i get the information at runtime, which mode (DMA on/off) the auart is running?
Can i enable or disable DMA mode at runtime for the auart?
Are there any disadvantages using DMA mode for mxs-auart?
Does the DMA mode support marking of parity and framing errors?
Is there more documentation about auart than in the reference manual for the EVK?
Thanks in advance
