Hello,

I hope you are doing great, I am facing the issue with NUCLEO-H743ZI2 Board, The LD6 is always ON and the IC U2 is getting overheated as soon as we connect the USB cable to dump the code and also unable to dump the code. It would be great if someone resolve the issue, Thanks for your attention.

Hello @Rohith1 and welcome to the community,

Not easy to give you an answer if you didn't tell what you did before that behavior to occur.

The heating means you have a hardware issue / shortcut etc.. may be you've broken something on the board may be in the power block.

On which part of the board the overheating is released?
