Hello,

I recommend that you create a new ticket for your issue, as this thread is quite old. Please include all your details in the new ticket, including the SDK version, complete logs, and overlay file.

Kind regards,

Abhijith

What version of NCS do you have? I have NCS v1.5.0 and I found it here: C:\Users\<user name>\ncs\v1.5.0\zephyr\drivers\flash\nrf_qspi_nor.c.

[quote user="MarcosDNordic"]Could you help us with one example for nrf5340 where only read and write some bytes, we can continue after that[/quote]

I think the sample C:\Users\<user name>\ncs\v1.5.0\zephyr\samples\drivers\spi_flash\src\main.c is a perfect fit. It does not use a file system, just pure flash write and read calls.

If the board nrf5340dk_nrf5340_cpuapp is used, the configurations in zephyr\samples\drivers\spi_flash\boards\nrf5340dk_nrf5340_cpuapp.conf will get automatically applied, which will make the driver nrf_qspi_nor.c get used under the hood. E.g. when flash_read() is called, the function qspi_nor_read() will get called under the hood. You don't need to worry about configuring the hardware, since qspi and the onboard flash is already set by default in the board file: zephyr/boards/arm/nrf5340dk_nrf5340/nrf5340_cpuapp_common.dts

Best regards,

Simon

I have checked the link.

This link has filesystem options, we are searching for something more simple. In this link, we have also a link to a library Here but when I try to search this library in the zephyr folder I do not find it.

Could you help us with one example for nrf5340 where only read and write some bytes, we can continue after that.

I think this ticket should be relevant: https://devzone.nordicsemi.com/f/nordic-q-a/72045/flash-filing-system-for-nrf-connect-sdk

Please ask if you have any more questions

Best regards,
