AM623: am623

Part Number: AM623
Tool/software:
Hello, I am currently debugging the audio function of the AM6234. The audio chip used on the board is the ES8388, connected to the main_i2c2 of the AM6234. The audio interface is connected to the mcasp0 of the AM6234. Hardware-wise, an external 11.2896 MHz crystal oscillator is connected to the MCLK of the ES8388 and the AUDIO_EXT_REFCLK1 of the AM6234. The schematic diagram is as follows:
The device tree configuration is as shown in the attachment.

After the system boots up, audio recording and playback are not working.
When using arecord to record audio, the following error is reported:
When using aplay to play audio, there is no sound, and the program hangs indefinitely until terminated with Ctrl+C.
Please help check if there is any issue with the device tree configuration. I am currently using Linux SDK version 11.00.09.04.

Hi Huan,
Since codec is master and providing the BCLK and Frame Sync, the pin configuration should be PIN_INPUT for ACLKX, FSX. Please refer our dts file for reference where our codec is providing the clocks to MCASP1.

Best Regards,
Suren

Hello, I have configured MCASP0_ACLKX and MCASP0_AFSX as inputs, but my issue remains the same as before—it still doesn't work.
