Since it is an ARM peripheral (as opposed to McBSP1 and McBSP3), then I expect it to be as follows. However, I get a timeout error. omap_set_dma_dest_params(cs4384_data.dma_tx_ch, OMAP_DMA_PORT_TIPB, OMAP_DMA_AMODE_CONSTANT, OMAP1610_MCBSP2_BASE + OMAP_MCBSP_REG_DXR2, 0, 0); If I change the code to use MCBSP1 (and MPUI as the port), all is well. Thanks, Steve
