Debugging SMT32定时器PWM输出仅在调试模式下工作

我使用stm32cube为stm32f105处理器生成了代码。这是一个使用adc，uart和定时器与pwm输出

在调试模式下运行代码时，一切正常。但是，当删除调试模式时，pwm输出不会改变

我将IAR用于ARM 8.22.1

我没有使用HAL_延迟。我已经更改了SysTick的优先级。改变了时钟频率。更改了链接器

代码应读取adc，并根据读取的值生成pwm。UART的其他功能正常工作。唯一不起作用的是pwm。

1）删除调试模式意味着什么？更改编译器设置（哪些设置？），或断开调试探测？2） 请提供一份报告。显然缺少启用外围设备（GPIO除外）、为引脚设置备用功能、更改PWM占空比的代码。3） 验证每个结构中的所有字段都已初始化。局部变量可能有不可预测的值，它们可能在调试环境中被初始化为

0

，但在发布版本中有一些其他值。4） 定时器主控和从控配置应该做什么？如果不使用它们，请将其删除。这看起来像是看门狗问题。IAR在进入调试模式时禁用看门狗。要测试这一点，只需注释

MX_WWDG_Init（）和<代码>HAL_WWDG_刷新（&hwwdg）和测试，无需调试。
