SDK DK devicetree file

Question

Hi, 
 I am taking the nRF Connect SDK Fundamentals course using the nRF7002DK board 
 Blinky file loaded modified and it is working. 
 But I can find no way to see the binding for led1 with GPIO P1.06 (LED1 in nRF7002DK) 
 This is the line in blinky 
 #define LED1_NODE DT_ALIAS(led1) 
 I looked in the following DTS files: 
 nrf7002dk_nrf5340_cpuapp.dts 
 nordic/nrf5340_cpuapp_qkaa.dtsi 
 The nrf5340_cpuapp_common.dts 
 nrf7002dk_nrf5340_cpuapp-pinctrl.dtsi 
 But no luck to spot the binding with GPIO P1.06 where the LED1 is attached. Where on earth is that? 
 Finding this I can move faster since I have stacked in moving in the SDK Fundamentals 
 Thank you

Hi Vasilis 
 You should not make changes to the board files directly. These are a part of the SDK, and should remain unchanged. 
 If you still need to change something you essentially have two options: 
 1) Make your own board definition based on the DK board files, and change them as you want. This is the recommended option if you are planning to make your own hardware (PCB) at some point. 
 2) Use an overlay to modify the board definition without altering the board files themselves. This is the recommended option if you are just testing things out, and when you are learning how things work. 
 In other words, if you do want to make changes it is to be expected that you have created an overlay. 
 Best regards Torbjørn

You welcome Vasilis, glad I could help out 
 The learning curve when starting out with the new SDK is quite steep, but we are working hard to make it easier to get into (the DevAcademy being an example of this). 
 Financially we are in a bit of a slump at the moment, but I believe strongly in our future, and expect many exciting products to be launched in the coming years 
 Please do keep in touch! 
 Regards Torbjørn
