STM32F303C8代码未进入while循环

我什么都试过了，在这里我真的不知所措

问题陈述： 代码不进入while循环

1.在STM32F303C8上工作

2.我有三个董事会：

Nucleo F303RE
Nucleo F303K8
Custom board.

它们都有相同的IC，并给出相同的问题。因此，问题一定与软件有关

我已经在BitBucket上发布了整个代码和cubeMX文件。请在此处找到链接：

代码只是拒绝进入while循环

如果删除了IWDG init函数，则代码仍停留在序列中的最后一个init函数调用处。若对IWDG进行了注释，它将跳回代码的开头，并一直执行到while循环的开头

可能是启动文件吗

提前感谢您的支持

我能够解决这个问题。 这很傻，但可能对刚开始使用HAL的人有所帮助。 正如old_timer所回应的，这个问题确实与时基有关

根本原因是： 计时器6正在初始化，但其计时器基数需要单独初始化。 解决方案： 调用函数

MX\u TIM6\u Init

后，集成函数

HAL\u TIM\u Base\u Start\u IT（&htim6）

。 这就解决了问题。还要注意的是，由于我在中断模式下使用定时器6，我需要HAL_TIM_Base_Start_IT功能。否则，您应该调用

HAL\u TIM\u Base\u Start

函数

亲切问候,

请发布相关代码，而不是链接。您确认正在通话的外围设备已启用时钟？如果您试图以重置或门控时钟方式访问外设，它可能不会响应，并可能挂起处理器。
