Hi All,
I am using 'NRF SDK v2.7 + NRF5340 DK + VSCode' and cloned a official nrf 'blinky' sample. The code and pins are working fine and I have verified using DK and logic analyzer. My confusion is since, I have defined a nrf5340dk_nrf5340_cpuapp.overlay in my project root directory and properly selected for 'build configuration' as well but my device-tree is not reflecting/updating as per my new 'nrf5340dk_nrf5340_cpuapp.overlay' file. As you can see even though relays node and pinouts are defined the device-tree is not reflecting them. It is always showing that 'nrf5340dk_nrf5340_cpuapp.dts' are being used and that 'Editing SDK file!' is not a good idea[which is true of course].
My question and need help is that I don't want that to happen I want to show and be in sync with the pinouts as per my 'nrf5340dk_nrf5340_cpuapp.overlay'
Please also see attached my full overlay file. Thank you
