Hi Nordic
My program can build pass, but it can lock nrf51822 . Do you know what error can cause it ?
I am looking forward to receiving you reply !
Have you changed the download function? Click Options for Target->Utilities->Settings Are "Erase Sectors" selected? If not, select it.
You can edit your question to include your complete project, then you must also say what SDK version and SoftDevice version you are using. If your project is secret, you should create a case in the MyPage support portal, and add it there.
The other way is to edit your question. Click "edit" below your question, attach your complete project and information about SDK and SoftDevice version.
