Hi, I'm currently using Nucleo-U575ZI-Q.
I've done nothing to it except leaving it for a day and just plugged it to my laptop again but it doesn't recognize my board now.
When I connect it with my laptop, fail.txt shows up with a message "The interface firmware FAILED to reset/halt the target MCU"
I figured out that the voltage supplied by the USB is 0.7V which is way lower than the operating voltage.
How can I fix this?
I'll add a photo that shows how it looks after I hook up with my laptop.
Also this is the error message from STM32CubeProgrammer(I tried to reset the firmware):

This is not enough voltage for the chip to run. Looks like your jumper settings are correct.
The board is probably damaged. You can look at the schematic to try and figure out what is damaged and replace it.
