Flashing problem using VS Code and NRF connect

[Quetzacoal]

Hello,

I will explain my workflow so you can understand my problem using VS code and assuming everything is installed correctly, I`m using SDK 2.7.0:

1. Create new project > copy from existing > blink example
2. Add build configuration > default > build configuration
3. Command > nrf connect: build > nrf connect: erase and flash

after this procedure the program is flashed into the board successfully however, when I read the memory it shows as empty. You can also see LED 2 is a little bit dimm. This happens every time I erase the memory.

My understanding is that nothing is being flashed

Am I missing something?

Thank you for your help

Hi this behaviour is common when one shifts to zephyr rtos nordic SDK in vscode  

please put this DCDC enable in your prj.conf file  

CONFIG_BOARD_ENABLE_DCDC=n

also disable or comment following configs if you have them on your deconfig file 

# CONFIG_USE_SEGGER_RTT=y

# CONFIG_LOG_BACKEND_RTT=y

Also if your LED is dim in your custom board I feel you are not powering your custom board from separate power source , which is necessary , 

Have a great day !

Thank you for your response

In the end I found the problem, was the selected board, for the nrf52 DK it should be selected as this image

The problem is solved
