Need support for PCm5242 Bringup

Hi Team,

We are working on PCM5242 Audio DAC with NXP processor in ANdorid11 code base.

I have integrated all the changes in DTSI and driver file.

After changes, DAC has been registered successfully.

I checked the all clocks like WCLK MCLK BCLK and DIN pin , We are getting all the clocks properly while playing audio file. But NO sound.

Error we are facing:

E audio_hw_primary: start_output_stream: Invalid PCM card id: -1
I audio_hw_primary: start_output_stream: primary: 1, out: 0xee944630, device: 131072, address: , mode: 0, flags 0x2
I audio_hw_primary: select_output_device(), headphone 0 ,headset 0 ,speaker 2
D audio_hw_primary: start_output_stream: pcm_open: card: -1, pcm_device_id: 0, rate: 48000, channel: 2, format: 0, period_size: 0xc0, flag: 9

Looks like no card present:

evk_8mm:/ # cat /proc/asound/card0/pcm0p/*
card: 0
device: 0
subdevice: 0
stream: PLAYBACK
id: 30050000.sai-pcm512x-hifi pcm512x-hifi-0

2. When trying to play audio file

DTSI changes:

};

pinctrl_sai5: sai5grp {
fsl,pins = <

MX8MM_IOMUXC_SAI5_RXD1_SAI5_TX_SYNC 0xd6 /*WCLK*/

};

NOTE: WE dont have proper driver. We are using driver of different family which is pcm5142.

Need your urgent support

Sorry, I don't have any reference.

First check in device/nxp folder [Files- audio_policy_configuartion and audio_effects.xml]. Then vendor folder[Audio HAL changes]

as per log its identifying your card id as -1. You need to update this in Audio HAL changes

FYI. Please read the Chapter 16 for audio codec porting.
