Hi,
Background
I’m currently developing an application that would gather data from a couple of sensors and send them either via LTE or WiFi depending on the WiFi availability. I want to use WiFi in order to save as much LTE data as possible.
To make a prototype of the solution I bought nRF9160 Feather and nRF7002-EB.
Current Status
I’m using NCS version 2.6.2 (but I tried also on 2.5.3).
Currently I have developed a simple program to gather the data from the LIS2DH and print the data using serial logs, everything works fine.
Now I started to configure the WiFi and I followed the Nordic DevAcademy WiFi Fundamentals course and I added a simple WiFi configuration plus a code for WiFi shell provisioning.
Error
When I try to build the program, linker throws an error that section 'text' will not fit in region 'FLASH', region 'FLASH' overflowed by 351524 bytes.
Build log:

I’ve tried to disable all logging and it saved around 50 kB, still it showed region 'FLASH' overflowed by 300000 bytes.
I’ve tried to configure the partitions in overlay file (see it’s commented in appendix). This didn’t improve anything. Maybe I’ve done it wrong, I’m not sure. For now, I’m not thinking about the FOTA and I’m only using the ns version, so I thought that I should be able to just use one slot which could be using the whole FLASH available.
Conclusions
I guess it should fit in the flash without a problem but now I’m a bit stuck how to configure it properly.
