NUCELO-F429ZI Encountered a issue.

When i connect a USB ,it is showing like FAIL and a message is shown on the screen like

The interface firmware FAILED to reset/halt the target MCU.

Can any one let me know what is the reason for this and solution for this.

Try with CubeProgrammer , set mode "under reset" , reset "hardware reset" , connect ;

then show , what it tells (screenshot).

So your board -> F429 cpu has no power.  Check jumper settings, see board manual.

Then connect again....
