Please post the Kconfig warnings from your build log here.

Hi I have added the same configurations in the prj.conf. I am facing an error " Aborting due to Kconfig warnings"

Then you can just copy the settings from the board configuration file ( https://github.com/nrfconnect/sdk-zephyr/blob/v3.6.99-ncs2/samples/drivers/spi_flash/boards/nrf5340dk_nrf5340_cpuapp.conf ) to your prj.conf file.

Hi I have to use prj.conf alone in configurations and need to execute for QSPI by adding the overlay file and all. Is there any solution for that.

You should see both configuration files if you use the 'build system default' if you use the original sample. The 'nrf5340dk_nrf5340_cpuapp' board is already configured to have the mx25r64 device on the QSPI bus. If you want to use SPI instead, you would need to create a device tree overlay to remove the flash device from the QSPI bus and move it to one of the SPI buses.

But when u select Use build system default in the configuration only nrf5340dk_nrf5340dk_cpuapp.conf is showing in the kconfig. If i am selecting prj.conf means it is not showing.

Hi,

I understand the confusion, but CONFIG_SPI symbol is actually set to '=n' in the board specific kconfig fragment here: https://github.com/nrfconnect/sdk-zephyr/blob/v3.6.99-ncs2/samples/drivers/spi_flash/boards/nrf5340dk_nrf5340_cpuapp.conf and this configuration takes precedence over the other.

If you are unsure if a symbol is selected, you can check the generated configuration file shown under 'Output files':

Thanks for the reply.

When I run the SPI Flash sample code, in prj.conf I can see only these configurations

CONFIG_STDOUT_CONSOLE=y

CONFIG_FLASH=y

CONFIG_SPI=y

QSPI is not enabled

Hello,

The QSPI NOR driver is used by default when you build the SPI NOR sample for the 'nrf5340dk_nrf5340_cpuapp' board. The QSPI and mx25r64 nodes are also enabled by default in the devicetree for this board.

Best regards,

Vidar
