Hello,

Iam using STM32H743 Nucleo board.

Suddenly The Red LED (Over current LED) is glowing in my Micro controller. I have cheked all the connections properly there is no short circuit in it.

Because of this i cant able to load the Program in it It is showing Target Not Found Error.

When i Checked the Data Sheet . it is written like if the board power consumption in the USB Exceeds 500 mA Then the LED will glow it seems .

i am powering with my laptop till today morning it was working fine. May i know what is the cause

Kindly give me the solution to get out of it.it will be very helpfull

Could be an issue with the port or cable.

Or that you've shorted something out, or damaged the board.

There is no need to attach manuals, a web link will suffice.

You could try connecting the BOOT pin to VDD if you think it is something related to code you recently uploaded.
