Hi,
I am sorry I didn't say this before. I am already using the setting
suggested by you.
Below is the detailed setting that I am using for configuring MCBSP0:
#define MCLK 27
#define DAVINCI_DMA_MCBSP_TX 2
#define DAVINCI_DMA_MCBSP_RX 3
#define DEFAULT_BITPERSAMPLE 256
#define AUDIO_RATE_DEFAULT 8000
output_stream.dma_dev = DAVINCI_DMA_MCBSP_TX
input_stream.dma_dev = DAVINCI_DMA_MCBSP_RX
/* MCBSP register settings for I2S */
spcr2 = FREE | XINTM(3),
spcr1 = RINTM(3),
rcr2 = RWDLEN2(DAVINCI_MCBSP_WORD_16) | RDATDLY(1),
rcr1 = RFRLEN1(1) | RWDLEN1(DAVINCI_MCBSP_WORD_16),
xcr2 = XWDLEN2(DAVINCI_MCBSP_WORD_16) | XDATDLY(1) | XFIG,
xcr1 = XFRLEN1(1) | XWDLEN1(DAVINCI_MCBSP_WORD_16),
srgr1 = FWID(DEFAULT_BITPERSAMPLE - 1),
srgr2 = FSGM | FPER(DEFAULT_BITPERSAMPLE * 2 - 1),
/* configure McBSP to be the I2S slave */
pcr0 = CLKXP | CLKRP,
/* MCBSP0 information */
struct davinci_mcbsp_info mcbsp_davinci = {
.virt_base = IO_ADDRESS(DAVINCI_MCBSP0_BASE),
.dma_rx_sync = DM355_DMA_MCBSP0_RX,
.dma_tx_sync = DM355_DMA_MCBSP0_TX,
.rx_irq = IRQ_MBRINT,
.tx_irq = IRQ_MBXINT
},
Is there any thing else that I will have to do?
Please help...
