Subject: Using the loop feature of the DMA controller on MPC8544 DS
Date: Wed, 12 Mar 2008 13:34:37 +0100	[thread overview]
Message-ID: <20080312123437.GA1589@Chamillionaire.breakpoint.cc> (raw)

Hello,

I have here a MPC8544 DS board and I tried to utilise the dma
controller. For the transfers I need set the [S|D]AHE bit in the Mode
Register. This seems to be implemented but is currently unused in the
driver. I haven't found a way how to set this bit except globally for
the whole channel.
Is it possible to solve this nicely except dedicating one channel for
such an operation?

thanks,
 Sebastian
