Hi,
I see.
Do you get the clocks(For Ex: 8KHZ) from TW2815 on CLKR PIN ? If not, there
is something wrong for configuaring TW2815 through I2C.

Hi Liu,
I am making driver for TechWell TW2835 chip. It is a audio/video mux.

Are you working with AIC33 on your daughter sound board ?

Hi,
I tried your suggestion. Still recording doesn't work. Anything else that
I need to try?
2009/3/4 <liuy...@covond.com>
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

DM355 is slave. below is configuration done for pcr0 and srgr2:
pcr0 = CLKXP | CLKRP
srgr2 = FSGM | FPER(DEFAULT_BITPERSAMPLE * 2 - 1)

Hi,
Does DM355 is the master ?
You should to do some settings for srgr2 and pcr0 because MCBSP0
has no CLKS PIN.
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

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...

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)
