问题描述
可能原因1：电脑蓝屏过一次，我尝试了重新安装zadig那个驱动
可能原因2：
调用了一段函数：
from machine import Pin
# 尝试遍历引脚默认电平
for index in range(0,64):
pin = Pin(index, Pin.OUT, pull=Pin.PULL_NONE, drive=7)
print(f"{index}={pin.value()}")
发现部分引脚提示如：
pin(2) is not a GPIO pin, func=101, Please notice it.
2=0
然后重新插拔上电后就反复枚举失败，启动不来，尝试了重新烧录固件，换TF卡无效果
（原理图里0-63引脚没有什么重要的东西啊，除了基础串口外设、boot、TF、摄像头和普通IO）
不插卡时，USB枚举成功显示K230 USB Boot Device，调试串口0打印
boot failed with exit code 19
插卡时不断重新枚举，调试串口0打印：
\0

提示USB有问题，但是通过USB又可以烧录固件，但是正常启动就不可以
