简单点亮LED都hard fault了

单片机型号是STM32F070RBT6，自己做了一块板子，做一些AD检测、数据存储、USB、UART通信等功能。
由于对单片机研究不是很多，使用cubemx生成初始程序，但是测试发现很严重的hard fault。
于是就把所有的东西都关掉了，只保留PB12翻转PIO，看LED的点亮、熄灭。发现还是会hardfault。hard fault的原因无非就是数组越界，堆栈溢出等，这些我都没有涉及到，除了系统的中断外也没有开启什么中断，实在想不通为什么会出错。
下面是代码和电路图，所有的元件都是mouser买的，应该不会有假货。麻烦大家帮我看看是哪里犯了什么低级错误。/**

按照外部晶振8MHZ：
RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
不是
RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV2;

可以去参考以下资料
【stm32f070RBT6开发,系统总是进入hardfault中断】
【STM32F0 M0 向结构体赋值进入HardFault异常】
【操作内部FLASH导致进入HardFault】
【stm32出现HardFault,应该如何解决】
希望对你有帮助

多谢啦。
现在在开发板上跑程序是好的，所以我怀疑是硬件问题。
但是板子又是照着nucleo布的……

确定
有“ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;”
HSE是好的。

多谢，我去检查一下。
应该是好的，晶振是在mouser买的。开发板上焊的是淘宝货都没问题的。

时隔一个月，回来总结一下：
1 温度太高会导致死机
2 Flash等待周期不能设置为0，要根据电压和HCLK进行设置，cubemx有点坑，直接设置为0了
