Greetings,
We are planning to integrate the use of the internal storage of our nRF52840 MCU using LittleFS so we tried starting out by just opening the sample zephyr/samples/subsys/fs/littlefs and after adding the nrf52840dk_nrf52840 board in the build configuration and building the project the build was not successful and the following error was shown at the output terminal:

What could be causing this? We just build a sample as it was in the SDK (no changes just created a new application with the sample as the 'Application template', selected the nrf52840dk_nrf52840 board in the build configuration and pressed build).
Thank you!
Best regards,
Stavros
