debug/Memfault sample doesn't work out-of-the box

Question

Hi Nordic Team, 
 I hope this message finds you well. I'm working with the SDK & Toolchain at version 2.5.0 and attempting to run a sample using the 7002DK. 
 The specific sample I'm trying to execute is the Memfault demo, detailed at https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/debug/memfault/README.html . 
 However, I'm encountering an issue where the sample fails to build. I've followed the provided documentation and configuration instructions, but some information or steps might be missing to compile this sample successfully. 
 Could you please verify if the current documentation for this sample is complete or if additional steps are required for compatibility with the SDK & Toolchain version 2.5.0 and the 7002DK? 
 Your assistance in resolving this matter would be greatly appreciated. 
 Best regards, 
 Vincent

Hello Vincent, 
 I also followed the documentation to build the sample and I failed on my first attempt. I did not get the same errors as you did, but I will share what I did to remove my errors. 
 
 Added my Memfault project key to CONFIG_MEMFAULT_NCS_PROJECT_KEY in prj.conf.
 
 In case you missed it, this necessary modification was pointed out in the intro section of the documentation:

Disabled CONFIG_WIFI_CREDENTIALS_STATIC in nrf7002dk_nrf5340_cpuapp.conf. An alternative solution is to fill inn the SSID and password for your Wi-Fi network.
 
 The documentation about the Wi-Fi credentials configs made it seem like no change was needed if you did not want the DK to connect automatically to Wi-Fi on boot. Changing the default value for CONFIG_WIFI_CREDENTIALS_STATIC to 'n' matches the documentation better, so I will report the mismatch internally.

After the modification I built the sample in its original position in NCS. 
 If you have made those modifications and get the build error still. Please provide some more information: 
 
 Did you use the "Create a new application" option from the nRF Connect for VS Code extension? 
 Are you able to build the basic NCS samples? I.e. zephyr/basic/blinky . 
 
 Best regards, 
 Maria

debug/Memfault sample doesn't work out-of-the box
