I.mx8qm ESAI1 configuration (kernel version 5.4.24)

Hi,

Can you please help with enabling ESAI1 interface for imx8qm

My current configuration:

sound-xtor { compatible = "fsl,imx-audio-xtor"; model = "my_audio"; cpu-dai = <&esai1>; tx-codec-slave = <1>; rx-codec-slave = <1>; status = "okay"; }; &esai1 { #sound-dai-cells = <0>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_esai1>; assigned-clocks = <&acm IMX_ADMA_ACM_ESAI1_MCLK_SEL>, <&clk IMX_SC_R_AUDIO_PLL_0 IMX_SC_PM_CLK_PLL>, <&clk IMX_SC_R_AUDIO_PLL_0 IMX_SC_PM_CLK_SLV_BUS>, <&clk IMX_SC_R_AUDIO_PLL_0 IMX_SC_PM_CLK_MST_BUS>, <&esai1_lpcg 0>; assigned-clock-parents = <&aud_pll_div0_lpcg 0>; assigned-clock-rates = <0>, <786432000>, <49152000>, <12288000>, <49152000>; fsl,txm-rxs; status = "okay"; }; pinctrl_esai1: esai1grp { fsl,pins = < IMX8QM_ESAI1_FSR_AUD_ESAI1_FSR 0xc6000040 IMX8QM_ESAI1_FST_AUD_ESAI1_FST 0xc6000040 IMX8QM_ESAI1_SCKR_AUD_ESAI1_SCKR 0xc6000040 IMX8QM_ESAI1_SCKT_AUD_ESAI1_SCKT 0xc6000040 IMX8QM_ESAI1_TX0_AUD_ESAI1_TX0 0xc6000040 IMX8QM_ESAI1_TX1_AUD_ESAI1_TX1 0xc6000040 IMX8QM_ESAI1_TX2_RX3_AUD_ESAI1_TX2_RX3 0xc6000040 IMX8QM_ESAI1_TX3_RX2_AUD_ESAI1_TX3_RX2 0xc6000040 IMX8QM_ESAI1_TX4_RX1_AUD_ESAI1_TX4_RX1 0xc6000040 IMX8QM_ESAI1_TX5_RX0_AUD_ESAI1_TX5_RX0 0xc6000040 >; };

I see audio card: my_audio:

[ 5.844504] ALSA device list:
[ 5.847481] #0: my_audio
[ 5.850190] #1: imx-audio-hdmi-tx
[ 5.853680] #2: wm8960-audio

After running: tinycap /data/local/tmp/t.wav -D 0 -r 48000

I'm getting the output below:

[ 83.587989] fsl-esai-dai 59810000.esai-port: output freq of HCKR should not be 0Hz
[ 83.600402] imx-xtor sound-xtor: failed to set cpu sysclk: -22 tx = 0, ms_fmt = 16384, sysclk = 3, dir = 1
[ 83.610096] imx-xtor sound-xtor: ASoC: machine hw_params failed: -22

I expect to get correct capture t.wav with silence/

Also I tried to change configuration to ESAI0 for sound-xtor - but also got failed to set cpu sysclk: -22 error

Does ESAI work on Imx8qm with kernel 5.4.24 ?

Thanks

Hi Vitaly

one can try below dts and follow sect.7.1 Advanced Linux Sound Architecture (ALSA) System on a Chip (ASoC) Sound i.MX Linux Reference Manual

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8qm-mek.dts?h=lf-5.10.y

Best regards

Hi igor,

I can't use suggested dts because I don't have cs42888 codec.

Anyway, xtor should works with ESAI1 without errors, correct?

Could you confirm that ESAI1 and ESAI0 work on automotive-10.0.0_2.2.0-20200509 tag? Have you been established esai connection on this kernel version?

Thanks
