I encountered a similar problem with the nRF52840 DK board. Here is what it took for me to fix it.

1. Exit VS Code.

2. Connect the board to the computer and turn it on.

3. Start J-Link. It detects out of date version of the emulator and wants to update. Let it do this.

4. Exit J-Link.

5. Restart VS Code and try to flash again. My first flash failed and I was prompted to do `west flash --recover` before flashing again. The flash attempt after that worked.

Do you see any error message or logs?

The following document page from u-box page introduced how to check connect with JLINK directly. You can have a try.

Hi Charlie,

Thank you for your reply.

The ACTIONS window is not hidden but I can not flash my application.

Do you have any idea?

Thank you.

Hi,

I do not have too much knowledge about bmd-345-eval since it is not official Nordic product, but it looks quite like nRF52840DK.

It seems you did not build any project to prepare program in to this board. You can also right-click mouse to check if "ACTIONS" window is hidden.

Best regards,

Charlie
