Access to .dts file through adb shell

Open the dts file with text.
Using Linux system will be better.
Find out the uart you need to change, and match the key word, "uart"  and set"status=okay"

we are also trying the Linux way you suggested but in linux also we are not able to locate the path  ...

u should set "okay" uart in the source code. No access in adb shell command line. Usually, adb shell devicetree just provide interface for check there status. only few allow to change or access .

just modify the source code and recomplie them , reflash kernel and resource.

1. &uart0 {
   
2.         pinctrl-names = "default";
   
3.         pinctrl-0 = <&uart0_xfer &uart0_cts>;                                                                                                  
   
4.         status = "okay";
