A problem about tsc2101 omap audio alsa driver on H3 board

[Ningzhong Miao - 苗宁忠]

Kernel : 2.6.16

Patch: linux-2.6.16-omap1 from www.muru.com <http://www.muru.com/> 

Board: omap1710 H3

Rootfs : NFS

 

I don’t know why don’t define h3_mcbsp1_device in arch/arm/mach-omap1/borad-h3.c, but it is defined in board-h2.c.

So I copy the belowed data from board-h2.c to board-h3.c. 

 

static struct omap_mcbsp_reg_cfg mcbsp_regs = {

        .spcr2 = FREE | FRST | GRST | XRST | XINTM(3),

        .spcr1 = RINTM(3) | RRST,

        .rcr2  = RPHASE | RFRLEN2(OMAP_MCBSP_WORD_8) |

                RWDLEN2(OMAP_MCBSP_WORD_16) | RDATDLY(1),

        .rcr1  = RFRLEN1(OMAP_MCBSP_WORD_8) | RWDLEN1(OMAP_MCBSP_WORD_16),

        .xcr2  = XPHASE | XFRLEN2(OMAP_MCBSP_WORD_8) |

                XWDLEN2(OMAP_MCBSP_WORD_16) | XDATDLY(1) | XFIG,

        .xcr1  = XFRLEN1(OMAP_MCBSP_WORD_8) | XWDLEN1(OMAP_MCBSP_WORD_16),

        .srgr1 = FWID(15),

        .srgr2 = GSYNC | CLKSP | FSGM | FPER(31),

 

        .pcr0  = CLKXM | CLKRM | FSXP | FSRP | CLKXP | CLKRP,

        //.pcr0 = CLKXP | CLKRP,        /* mcbsp: slave */

};

 

static struct omap_alsa_codec_config alsa_config = {

        .name                   = "H3 TSC2101",

        .mcbsp_regs_alsa        = &mcbsp_regs,

        .codec_configure_dev    = NULL, // tsc2101_configure,

        .codec_set_samplerate   = NULL, // tsc2101_set_samplerate,

        .codec_clock_setup      = NULL, // tsc2101_clock_setup,

        .codec_clock_on         = NULL, // tsc2101_clock_on,

        .codec_clock_off        = NULL, // tsc2101_clock_off,

        .get_default_samplerate = NULL, // tsc2101_get_default_samplerate,

};

 

static struct platform_device h3_mcbsp1_device = {

        .name   = "omap_alsa_mcbsp",

        .id     = 1,

        .dev = {

                .platform_data  = &alsa_config,

        },

};

static struct platform_device *devices[] __initdata = {

        &nor_device,

        &nand_device,

        &smc91x_device,

        &intlat_device,

        &h3_irda_device,

        &h3_kp_device,

        &h3_lcd_device,

        &h3_mcbsp1_device,

};

 

These codes need to be modified ? mcbsp_regs is same with h2 ?? 

Anyway, I don’t modify anything.

I defined DEBUG in include/asm/arch/omap-alsa.h and defined CONFIG_MCBSP_DEBUG in arch/arm/plat-omap/mcbsp.c.

 

Then I run aplay in H3 board.

The program died here, and earphone don’t have any sound.

I have tried oss audio driver and 2.6.17 kernel. They are same.

 

Anybody come across this problem ?? help me, thank you !

Hmm, aplayer has newer crashed for me.
Could you first try to change the playback target from speaker (default)
to headphone by using alsa-mixer to check whether you can then hear
something? If crash still happens, could you try to remove debug,
change again the target to headphone with alsa-mixer and try again with
aplay.

Dear lamikr:

	It's same. The below is printed messages. The program stopped and no sound in STEREO HEADSET.
