Subject: OMAP5912 and McBSP2 with DMA
Date: Tue, 17 Jul 2007 05:55:03 -0500	[thread overview]
Message-ID: <469CA007.5090003@css-design.us> (raw)

Could someone tell me what the port should be for DMA with McBSP2?  
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
