Hello, sorry to disturb you I'm using Nrf52840 board and I would like to know how to flash correctly.
I'm going to tell what i did with Visual Studio Code.
I created a simple application with the sample Bluetooth Peripheral UART,
Then I did the boules configuration with the board that I wanted,
Finally when I try to build it's ok but when I tried to flash my card this is what happened:
" ERROR: or does not have data in valid areas.
best regards
