Are you working with AIC33 on your daughter sound board ? ----- Original Message ----- From: Azam Ansari To: [email protected] ; [email protected] Sent: Wednesday, March 04, 2009 4:34 PM Subject: Re: DM355 daughter sound card problem
Hi, I tried your suggestion. Still recording doesn't work. Anything else that I need to try? 2009/3/4 <[email protected]> Try the following to set CLKX PIN as CLKS PIN for recoding. initial_config.srgr2 = initial_config.srgr2 | CLKSM; initial_config.pcr0 = (initial_config.pcr0 | SCLKME); SCLKME CLKSM Input Clock For Sample Rate Generator 0 0 Signal on CLKS pin 0 1 ASP internal input clock 1 0 Signal on CLKR pin 1 1 Signal on CLKX pin ----- Original Message ----- From: Azam Ansari To: [email protected] ; [email protected] Sent: Wednesday, March 04, 2009 2:28 PM Subject: Re: DM355 daughter sound card problem DM355 is slave. below is configuration done for pcr0 and srgr2: pcr0 = CLKXP | CLKRP srgr2 = FSGM | FPER(DEFAULT_BITPERSAMPLE * 2 - 1) 2009/3/4 <[email protected]> Hi, Does DM355 is the master ? You should to do some settings for srgr2 and pcr0 because MCBSP0 has no CLKS PIN.

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... 2009/3/3 <[email protected]> Hi， I know your means. Following codes are used for configuaring MCBSP0 on my board: input_stream.dma_dev = DM355_DMA_MCBSP0_RX; output_stream.dma_dev = DM355_DMA_MCBSP0_TX; #define MCBSP_DXR (cpu_is_davinci_dm355() ? 0x01E02004:0x01E04004) #define MCBSP_DRR (cpu_is_davinci_dm355() ? 0x01E02000:0x01E04000) > Hi, > > I am using MCBSP0 for I2S data transfer.
