xtensa_write_memory(): address 0x400d2d33 not writable

Hi Team

I am trying to debug esp-idf/examples/blink project using Ecplise IDE following https://www.youtube.com/watch?v=NP5OjxytYQI&t=454s.

But after I debug and switch to debug perspective I get this error :

and I am not able to understand where to change and what to change.

Any assist would be helpful.

Thanks
