Hi all,
I'm try to use TLV320AIC3254 <http://www.ti.com/product/TLV320AIC3254> Audio Codec with Beaglebone Black. I face some issues when I set the BCLK frequences. Below is hw_params: static int tlv320aic32x4_hw_params(struct snd_pcm_substream *substream, struct snd_pcm_hw_params *params) { struct snd_soc_pcm_runtime *rtd = substream->private_data; struct snd_soc_dai *codec_dai = rtd->codec_dai; struct snd_soc_dai *cpu_dai = rtd->cpu_dai; struct snd_soc_card *soc_card = rtd->card; int ret = 0; struct platform_device *pdev = to_platform_device(soc_card->dev); unsigned int bclk_freq = evm_get_bclk(params); unsigned sysclk = ((struct snd_soc_card_drvdata_davinci *) snd_soc_card_get_drvdata(soc_card))->sysclk; printk("TLV320AIC32X4 hw params\n"); printk("sysclk=%d\n", sysclk); printk("bclk_freq=%d\n", bclk_freq); printk("clkdiv=%d\n", sysclk/bclk_freq); /* set the CPU system clock */ ret = snd_soc_dai_set_sysclk(cpu_dai, 0, sysclk, SND_SOC_CLOCK_OUT); if (ret < 0) return ret; /* set the codec system clock */ ret = snd_soc_dai_set_sysclk(codec_dai, 0, sysclk, SND_SOC_CLOCK_OUT); if (ret < 0) return ret; return ret; } The setting default is 1,4112 MHz for 16 bit stereo. I want to set this value for 32 bit stereo, it's 2,8224 MHz. I dont know how can I do that?
