Hi，Simon

thanks for reply.

i created file nrf52840dk_nrf52840.overlay as follow:

i connect  P1.13 to P1.14,

reload project and rebuild, it still runing whit old pin.

it means nrf52840dk_nrf52840.overlay not used.

but,when i delete folder build_nrf52840dk_nrf52840

and recreated,the pin had changed.

I don't know why, it's too much trouble.

   

thanks

Best Regards

Building an NCS/Zephyr project happens in two phases:

• Configuration phase
  • This is driven by CMake and will go through all the Kconfigs, prj.conf, .dts and .overlay files and generate the ninja files
  • If you change the prj.conf or .overlay file, you need to run this
• Build phase
  • This is driven by ninja and will only see the changes done to the .c/.h files
  • If you change fore example main.c it is enough to run this

When you rebuild the project in SES, it will only run the Build phase, check out the ticket SEGGER Embedded Studio Nordic Edition for NCS doesn't update .config for modified prj.conf to see how to run configuration phase+build phase.

However, you did say that you reloaded the project, so it's strange that it didn't work then

i've got it,

It's a little difficult from SDK to NCS.
