nRF5340-DK problem starting own project ncs v1.5.0

Question

HI 
 I'm in the process of evaluating nRF5340 but am new to Nordic chips and development environment. Im running Windows 10 and I installed nRF Connect 3.6.1 and installed the toolchain through it. 
 I managed to run the blinky proiect but have problems starting an own project. 
 I followed this guide 
 https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-1-ncs-v1-4-0 
 but when I build, I get this error

 I have spend several days on this problems and looked around but cannot find a solution. I would be very happy for any hint. 
 Does it matter that the example uses version 1.4 and I have 1.5? 
 Best regards,

Hi again! #1 Did you also try to reopen the project with a "Clean build folder"? This is usually required when changing the DTS. #2 As I mentioned earlier configuration of projects is essentially done through two manners; Kconfigs and devicetree overlays. - Kconfigs are a the options that can be configured for the different components of the SDK. In applications the default Kconfigs can be changed by editing the prj.conf file of the project (which is located in the project folder). In the same manner you can have different .conf file in a project for different configurations. For temporary configuration change in SES you can go to "Project"->"Configure nRF Connect SDK project". This opens a window where you can search for and select the various configurations(Kconfig) for the project. As explained in the documentation on Configuring your application you can change configuration permanently by changing the prj.conf file in the project directory. - Devicetree overlays are project files of the following format: .overlay . These are used to configure the available hardware resources of the target board. Take this I2C configuration as an example: &i2c2 { status = "okay"; compatible = "nordic,nrf-twim"; sda-pin = <10>; scl-pin = <11>; clock-frequency = <100000>; }; The configurable properties for the different HW resources can be found in the device tree bindings overview . The NCS/Zephyr development environment might come off as a bit overwhelming, and you have my apologies for that. I believe the best approach to get familiar with the SDK is to study existing samples and how they are set up, specifically looking at the project files, including .conf and .overlay. #3 This may take of a bit of topic and I suggest opening a new case for a more elaborate answer, but the best approach will likely be to start out with one of the Zephyr USB samples and then add support for a MEMS microphone using the Audio DMIC API . I see that there already are a couple of simple USB Audio samples with pre-existing configuration for the nRF5340 and nRF52840. Hope this answers some of you questions. Best regards, Carl Richard
