Pin Assignment Overwrite for adc

I don't trust the "Problems" tab in VS Code, as this doesn't necessarily pick up all the configurations for the project. Does the build log mention any errors? Does the log when running the application mention any errors? Does it work with all 8 channels?

BR,

I have tried it, it do not through any build error but there are some overlapping and unknown node problems in the problem window. can you please help me how to resolve this?....or does this cause any issue in communication?

Ok, I see. I believe the issue is that what you are trying to delete is a property, and not a node. So either you can delete the uart0 node:

/ {
    pinctrl: pin-controller{
        /delete-node/ uart0;
    };
    
    zephyr,user {
		io-channels = <&adc 0>, <&adc 1>, <&adc 2>, <&adc 3>, <&adc 4>, <&adc 5>, <&adc 6>,  <&adc 7>;
	};
};

Or you can delete the uart0_default and uart0_sleep properties:

/ {
    pinctrl: pin-controller{
        /delete-property/ uart0_default;
        /delete-property/ uart0_sleep;
    };
    
    zephyr,user {
		io-channels = <&adc 0>, <&adc 1>, <&adc 2>, <&adc 3>, <&adc 4>, <&adc 5>, <&adc 6>,  <&adc 7>;
	};
};

Also note that I removed the '&' before "uart0" in all cases.

When doing these changes, it builds here.

Best regards,

Yes, I am using the same sample. I had also copied the nrf52840 overlay file for nrf52832.

Hello,

There is a sample found in:

ncs\zephyr\samples\drivers\adc\

that is set up pretty much like you did here. I can't spot any immediate errors from what you have included here (other than the build log, of course), but does this sample work if you try to build it? Remember to copy the nrf52840dk_nrf52840.overlay file found in adc\boards and name it nrf52dk_nrf52832.overlay.

If you are still stuck, can you please .zip and upload your application folder here?

Best regards,

Edvin
