Getting Write verify failed every time when try to debug or write without erase.

[Jithin A]

Hi,

We are working with nRF5340 with SDK v2.5.2.

Each time we try to program the board, we get below error.

We do not see this error if we try Erase and Flash option from VS Code. We observe the same issue even with the nRF5340DK board.

This is very annoying us as we cannot debug or program without erasing. Please help us solving the issue.

We are using VS Code with NRF Connect extensions. SDK v2.5.2.

Thank you for the answers. About the last one, west error: did you try to run it specifically from nRF Connect terminal inside VS Code?

Our nRF Connect for VS Code extension should set up all the environmental variables for you automatically.

Best regards,

Michal

--> Yes, tried on both VS Code terminal and command prompt (with ADMIN access) and I see the same error.

--> How can I confirm this on my end?

From the VS Code, please try generating support information. It's the headset icon in the welcome view, please check here:

Thank you, I will look if I can find any issues there.
