Hello Nordic team,
I am trying to use external flash on nRF52840dk using Qspi.
// To get started, press Ctrl+Space (or Option+Esc) to bring up the completion menu and view the available nodes.
// You can also use the buttons in the sidebar to perform actions on nodes.
// Actions currently available include:
// * Enabling / disabling the node
// * Adding the bus to a bus
// * Removing the node
// * Connecting ADC channels
// For more help, browse the DeviceTree documentation at https://docs.zephyrproject.org/latest/guides/dts/index.html
// You can also visit the nRF DeviceTree extension documentation at https://docs.nordicsemi.com/bundle/nrf-connect-vscode/page/guides/ncs_configure_app.html#devicetree-support-in-the-extension

Above is my overlay file.

Above is my pm_static file.
I am using custom board where I have define the details for external flash.
Below is my proj_minimal.conf file

I am getting below error when I use it in my init_nvs_function (attached above):
Can you tell me where I am doing wrong?
Thanks for your support.
