Target not found on cubeide

[MSadf.1]

I'm working with a stm32 nucleo H723ZG board. Until yesterday everything worked fine, I could program the board and everything worked well. When I tried to connect my board to my PC today, cubeide could not find the board when I tried to run my program. I did not change any settings. The COM led stays red ( ld4 led ) and the ld6 led stays red aswell and no other leds are on. I tried to erase everything with the cube programmer but I got the error no target found when I tried to connect. here the text I got.

Try to change the Reset option to Hardware or to None.

I already did that and it didn’t work

When the voltage at the target is 0.25V and LD6 is lit, the NUCLEO-H723ZG draws more than 500mA from USB (see UM2407, section 6.6.1). You should check which additional devices you have connected to the NUCLEO.

the board isn’t connected to anything

[Peter BENSCH]

Well, I assume it's connected to a host with USB, right? 😉

But if you haven't connected anything, you'd have to find out why the overcurrent detection has tripped. LD6 is controlled by U2 (STMPS2151STR), which switches CN1.1 (VBUS) to the signal 5V_USB_CHGR.

On a conductive surface or conductive foam that might create a short-circuit, or regulator failure?
