Re: Problem when Flashing mesh_demo sample

When I have seen that error the first thing I try is running the command “ nrfjprog -r” this should successfully reset your board, if it doesn’t then you have a hardware problem, check your connections. 

If it has never worked then you probably need to update your jlink libraries. The latest version on the Segger site works with the latest versions of windows. But the version distributed with the Nordic tools doesn’t always work.
