Hello @ClearVoiceM from logs, it seems, your are flashing the firmware build for different board(viz., lyratd_vaquita).
Please remove the build, export AUDIO_BOARD_PATH to lyratd_dspg board and check.

Hi Vikramdattu,
Thanks for the help. After changing the AUDIO_BOARD_PATH it worked perfectly well.
Now can i capture raw PCM mic data into a raw/wav file(rawpcmdata.raw) and analyse the mic data. If yes how to do it? Can you pls help.

Thanks

Hi @ClearVoiceM the SDK itself doesn't provide you with this option. However, if you are keen, you may do some changes in the code to achieve the same.
My favourite is to create a http server (this will need 4 more sockets, so you have to increase MAX sockets as well), and send the data to the cloud from here: https://github.com/espressif/esp-va-sdk/blob/master/components/audio_hal/va_dsp.c#L152
