Could you be a tad more precise, which DSP and what revision? Since I know Prodys is working with TI DSPs, you might want to look into the silicon bug lists. With certain TI DSP, you will not be able to use DMA initiated by the PPC. Been there done that ;) ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
