Good Day.
I'm trying to run the "npm1300_fuel_gauge" example on a custom board (nRF52840), but I'm getting errors that I don't know how to fix.
The first thing I did was to get the PMIC configuration overlay file (config.overlay) through nPM PowerUP. Then I transferred the code from config.overlay to the custom board device tree file (custom_board_nrf52840.dts). I plan to connect the PMIC via I2C1.

};
The following errors occur in the .dts file (see screenshot).
I know that these values should be taken from the "fuel_gauge.h" file, but that doesn't happen for some reason.
I see an error in the prj.conf file too (see screenshot).
When building the project, I see the following information -->
I have not changed the CMakeLists.txt files.

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(my_npm1300_fuel_gauge)
add_subdirectory(src)
Can you please tell me where I am making a mistake when transferring this example to my custom board?
Thank you.
