Hi,
I am using an nrf5340DK + nrf7002EK. i am able to run an example helloworld application with an immutable bootloader and mcuboot as platform bootloader. When i try to add the wifi code, im getting an error stating that the internal flash doesnt have enough memory to run the application, which is understandable. So i tried to have XIP enabled. What i see here from the memory report is that ncs folder is consuming a lot of space. Is there a way where i can relocate the entire application code and ncs code to the external flash and run the application?
This is my prj.conf. I have disabled the wifi related code for now. its just the XIP and Bootloader code that is enabled
