Facing issue while debugging

Hi, I've been trying to debug my led toggle code. But I'm getting error like "Error in final launch sequence" and "Failed to execute MI command". I was using STM32F769-Disco board.

"like" ?

Please be specific: post the actual, complete message you are getting - a screenshot and/or copy & paste from the output log.

Are you sure that your computer is actually seeing the Disco board's ST-Link?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

You can paste into the post - then we can see it more easily:

So it's failing to load the .elf file - ie, your code.

Does that .elf file actually exist? Did you successfully build your project?

And, again, are you sure that your computer is actually seeing the Disco board's ST-Link?

If your computer can't see the ST-Link, then it's clearly not going to be able to use it to load your code...
