Can you open a new case about this, since this is not related to this ticket (external flash)

[quote user="Mr.NCK"]write the data as audio (.wav) file in external flash[/quote]

Check out the SPI Flash sample

Is there any sample for the below case?

Audio acquisition from I2s and write the data as audio (.wav) file in external flash

Yes, this should be possible. However, the sample SPI Flash sample does not use a file system, so you would need to control the content yourself and know at what address you store stuff.

But for this simple use case, you don't need a file system.

The easiest is probably just to start with the SPI Flash sample, which support the nRF53 DK: https://github.com/nrfconnect/sdk-zephyr/tree/v2.4.99-ncs2/samples/drivers/spi_flash/boards .

Check out this case for more information about this: https://devzone.nordicsemi.com/f/nordic-q-a/72045/flash-filing-system-for-nrf-connect-sdk,

In the above link I also attached a sample using the NVS filesystem.

Best regards,
