Hello,
I am using the STM32H743ZI Nucleo board.
Suddenly The Red LED (Over current LED) is glowing in my Microcontroller. I have checked all the connections properly, and there is no short circuit.
Because of this I can't able to load the Program in it It is showing a Target Not Found Error.
" STMicroelectronics ST-LINK GDB server. Version 7.7.0

Starting server with the following options:

Status Refresh Delay: 15s
Verbose Mode: Disabled
SWD Debug: Enabled
InitWhile: Enabled
Target no device found
Error in initializing ST-LINK device.
Reason: No device found on target."
When I Checked the Data Sheet. it is written that if the board power consumption in the USB Exceeds 500 mA Then the LED will glow it seems.
I have been powering with my laptop till this morning it was working fine. May I know what is the cause?
Thank you

Hello @Ramachandran1992 ,
Maybe you have a wrong power mode setting. Did you change SMPS/LDO settings?
Check with this article the steps on how to recover from such situation :
