Hello Naeem Maroof

There is already code to disable uart1 in C:\ncs\v2.6.1\zephyr\boards\arm\nrf9160dk_nrf9160\nrf9160dk_nrf9160_ns.dts,

And I have also tried disabling uart1 in overlay

But it didn't work, and the ADC values of those channels were still abnormal, I also checked zephyr.dts and it shows that uart1 is indeed disabled

[quote user=""]there is no need to make any modifications to nrf9160dk_nrf9160_common.dtsi[/quote]

_common.dtsi file shows the device tree of the SoC, and we can see that uart1 is enabled

If your application does not need uart1 then you can add the following in the overlay and it will be disabled

&uart1 {
	status = "disabled";
};

and you could confirm it from the compiled dts (in ./build/zephyr/zephyr.dts)

Hello Naeem Maroof

I am using version 2.6.1, and the example I used are C:\ncs\v2.6.1\zephyr\samples\drivers\adc and C:\ncs\v2.6.1\nrf\samples\cellular\http_update\application_update

Hello,

[quote user=""]using the application_update example for testing[/quote]

can you provide the link to both of these sample you are referring to? For both samples, are you using ncs 2.6.1?

I am not sure, but I can have a look at it. It could be that uart is being used for logging etc.
