Needs to get started with onboard external flash on Nrf5340dk

[Mr.NCK]

HI,

 I need to work on external flash memory which is placed on Nrf5340. I need to know where is the sample application to know the interfacing basics and I need to know. Can I need to short any bridge to work on the external flash?

Thanks & Regards

Navin

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,

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 .

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

Best regards,

Simon

Hey Simon, 

I need to write an audio file. I think I can achieve this by the above example. just tell me is it possible?.

[Simon]

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.

Is there any sample for the below case?

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

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