你好
我正在与 STM32H755BIT3 一起做项目。
我设计的电路板的现状是，用DC-DC 3.3V电源上电后，芯片很快发热严重，不出现短路就无法下载程序。我推测这是由于外围电路的设计。
有人可以帮忙找出问题所在吗？
提前感谢大家的任何提示。

Hello
I am working on a project with the STM32H755BIT3.
The current situation of the board I designed is that after powering up with a DC-DC 3.3V power supply, the chip quickly heats up severely and the program cannot be downloaded without a short circuit. I have a doubt about the hardware.
Can anyone help to find out what the problem is?
Thank you all in advance for any tips.
