Greetings,
I recently started working with the NCS and successfully modified the peripheral_uart sample to read data form an I2C sensor and send it via BLE
I wanted to make a brand new project using this code for the development phase of our newest FW for our product so I created an new application and then copied and pasted the source files as well as the CMakeLists.txt, prj.config, app.overlay files to the new directory.
The build (with nRF52840DK_nRF52840 board configuration as in the first sample I used) was successful and everything looked normal.
The next step was to create the custom board of our product which also had a successful build.
After modifying the .dts to include the i2c (same as in my first attempt) and adding the pinctrl.dtsi file by adding the following code:
.dts file snippet added
&i2c0 {
compatible = "nordic,nrf-twi";
status = "okay";
pinctrl-0 = <&i2c0_default>;
pinctrl-1 = <&i2c0_sleep>;
pinctrl-names = "default", "sleep";
};
xxxxxx-pinctrl.dtsi
i2c0_default: i2c0_default {
group1 {
psels = <NRF_PSEL(TWIM_SDA, 0, 6)>,
<NRF_PSEL(TWIM_SCL, 0, 5)>;
/* bias-pull-up; */ //Vital for I2C to work properly
};
};
i2c0_sleep: i2c0_sleep {
group1 {
psels = <NRF_PSEL(TWIM_SDA, 0, 6)>,
<NRF_PSEL(TWIM_SCL, 0, 5)>;
/* bias-pull-up; */
low-power-enable;
};
};
The building process halted with the error:
C:\ncs\v2.1.0\zephyr\include\zephyr\toolchain\gcc.h:77:36: error: static assertion failed: "/soc/i2c@40003000 defined without required pin configuration"

Do I need to somehow enable PINCTRL as the message says ?
How is this done?
Thank you very much for your time,
Best regards,
Stavros
