I am trying to get the beagleboardxm to work with an external codec. I am trying to use a mcbsp1 via the trainer board where it level shifts to 5 volts. I have applied this patch (I am on 2.6.39rc4), but still no joy. I have a small analyzer attached to the I/O pins and important things like the bit clock does not wiggle. First a side question. In the arch/arm/mach-omap2/Kconfig when I select BEAGLE, it selects OMAP_PACKAGE_CBB - but my bbxm system reference manual says "The BeagleBoard-xM processor is the DM3730CBP 1GHz version" which to me implies the proper package selection should be OMAP_PACKAGE_CBP. The platform file mux34xx.c has different tables for them, but I cant quickly tell the difference. Does this matter for mcbspx? Here is a console dump where I try to aplay a file: [ 1565.773712] omap_mcbsp_dai_startup: omap-mcbsp-dai.0 bus_id=0 active 0 [ 1565.781829] omap_pcm_open: ret 1 [ 1565.785491] asoc: HiFi <-> omap-mcbsp-dai.0 info: [ 1565.790527] asoc: rate mask 0x7fe [ 1565.794006] asoc: min ch 1 max ch 2 [ 1565.797760] asoc: min rate 8000 max rate 96000 [ 1565.826721] bbxm_hw_params: codec_dai=dfbbb9c0 clk 12288000 [ 1565.832702] bbxm_hw_params 2: codec_dai=dfbbb9c0 clk 12288000 [ 1565.838867] omap_mcbsp_dai_set_dai_fmt: configured 0 [ 1565.844146] bbxm_hw_params 3: codec_dai=dfbbb9c0 clk 12288000 [ 1565.850219] omap_mcbsp_dai_set_dai_sysclk: mcbsp_data=bf00d5b8 in_freq 0 [ 1565.857299] omap_mcbsp_dai_set_dai_sysclk: mcbsp_data=bf00d5b8 in_freq 0 [ 1565.864379] omap_mcbsp_dai_set_dai_sysclk: mcbsp_data=bf00d5b8 in_freq 2048000 [ 1565.877319] max98095 4-0010: read 2a => 10 [ 1565.884277] max98095 4-0010: read 27 => 1 [ 1565.891143] max98095 4-0010: read 2a => 10 [ 1565.898956] max98095 4-0010: read 2e => 0 [ 1565.903198] omap_mcbsp_dai_hw_params: format 1 [ 1565.907958] omap_mcbsp_dai_hw_params: stream Audio Playback [ 1565.913909] omap_mcbsp_dai_hw_params: framesize 32 in_freq=2048000 div=8 rate=8000 [ 1565.921936] omap-mcbsp omap-mcbsp.1: Configuring McBSP1 phys_base: 0x48074000 [ 1565.929565] omap_pcm_hw_params: ret 0 [ 1565.934722] omap_pcm_prepare: dma_data bf00d4a0 [ 1565.945831] max98095 4-0010: read 91 => 0 [ 1565.950347] max98095 4-0010: write 91 = 3 [ 1565.958618] max98095 4-0010: read 91 => 3 [ 1565.963195] max98095 4-0010: write 91 = c3 [ 1565.972351] snd_pcm_lib_write1: state 2 size 1000 [ 1565.977691] snd_pcm_lib_write1: offset 0 [ 1565.981842] snd_pcm_update_state: stream=0 avail=3000 buffer_size=4000 twake=0 tsleep=1 [ 1565.992706] snd_pcm_lib_write1: state 2 size 1000 [ 1565.997985] snd_pcm_lib_write1: offset 0 [ 1566.002227] snd_pcm_update_state: stream=0 avail=2000 buffer_size=4000 twake=0 tsleep=1 [ 1566.011810] snd_pcm_lib_write1: state 2 size 1000 [ 1566.017120] snd_pcm_lib_write1: offset 0 [ 1566.021270] snd_pcm_update_state: stream=0 avail=1000 buffer_size=4000 twake=0 tsleep=1 [ 1566.033050] snd_pcm_lib_write1: state 2 size 1000 [ 1566.038360] snd_pcm_lib_write1: offset 0 [ 1566.042510] snd_pcm_pre_start: state 3 [ 1566.046447] snd_pcm_do_start: state 3 [ 1566.050292] omap_pcm_trigger: cmd 1 [ 1566.053955] omap_start_dma: lch 0 [ 1566.057891] omap-mcbsp omap-mcbsp.1: **** McBSP1 regs **** [ 1566.063629] omap-mcbsp omap-mcbsp.1: DRR2: 0x0000 [ 1566.068664] omap-mcbsp omap-mcbsp.1: DRR1: 0x0000 [ 1566.073699] omap-mcbsp omap-mcbsp.1: DXR2: 0x0000 [ 1566.078735] omap-mcbsp omap-mcbsp.1: DXR1: 0x0000 [ 1566.083740] omap-mcbsp omap-mcbsp.1: SPCR2: 0x02f5 [ 1566.088775] omap-mcbsp omap-mcbsp.1: SPCR1: 0x0030 [ 1566.093811] omap-mcbsp omap-mcbsp.1: RCR2: 0x8041 [ 1566.098846] omap-mcbsp omap-mcbsp.1: RCR1: 0x0040 [ 1566.103851] omap-mcbsp omap-mcbsp.1: XCR2: 0x8041 [ 1566.108886] omap-mcbsp omap-mcbsp.1: XCR1: 0x0040 [ 1566.113922] omap-mcbsp omap-mcbsp.1: SRGR2: 0x101f [ 1566.118927] omap-mcbsp omap-mcbsp.1: SRGR1: 0x0f07 [ 1566.123962] omap-mcbsp omap-mcbsp.1: PCR0: 0x0f0f [ 1566.128997] omap-mcbsp omap-mcbsp.1: *********************** [ 1566.134918] snd_pcm_post_start: state 3 [ 1566.138977] snd_pcm_update_state: stream=0 avail=0 buffer_size=4000 twake=0 tsleep=1 [ 1566.148681] snd_pcm_lib_write1: state 3 size 1000 [ 1566.153625] omap_pcm_pointer: offset 64 [ 1566.157653] snd_pcm_update_hw_ptr0: old_hw_ptr=0 pos=64 in_int=0 [ 1566.163970] snd_pcm_update_hw_ptr0: stream=0 new_hw_ptr=64 silence_size=0 [ 1566.171081] snd_pcm_update_state: stream=0 avail=64 buffer_size=4000 twake=1000 tsleep=1 [ 1566.180145] snd_pcm_lib_write1: offset 0 [ 1566.184295] snd_pcm_lib_write1: state 3 size 936 [ 1566.189147] omap_pcm_pointer: offset 64 [ 1566.193176] snd_pcm_update_hw_ptr0: old_hw_ptr=64 pos=64 in_int=0 [ 1576.194274] ALSA sound/core/pcm_lib.c:1795: playback write error (DMA or IRQ trouble?)
