Hi,
I am working on TX49(MIPS) Target Board, where it supports DMA operation
for 4 channels. Presently the SIO is working in normal CPU mode (not
dma). Now I need to implement the DMA for my two SIO's. for this I need
4 DMA channels. Also I need to support ACLC(audio) on DMA which uses 2
channels. But actually I have only 4DMA channels. So How shall I share
DMA channels between these? Please Guide.
Thank You,=20

Swamy
