如题 ，库初始化GUI_Init（）调用时，在GUI任务创建后，osKernelStart();启动前，被调用，会使systick中断不触发，但中断配置什么都对，systick计数器也在走，就是不中断。最后卡死在延时那。
BSP初始化代码HAL_Delay（）函数中。
GUI_Init（）放在GUI任务运行里面调用，显示及其他运行一切正常，找了好久找不到原因，求解，谢谢大家了
main初始化部分，分三部分代码麻烦分析，main调用，BSP部分，GUI初始化部分
- <div class="blockcode"><blockquote>int main(void)
- {
- /* STM32F4xx HAL library initialization:

- HAL_Init();

GUI的初始化代码
- void init_gui(void)
- {
- GUI_Init();
- GUI_SetFont(&GUI_Font32_ASCII);
- GUI_DispStringAt("Starting...", 0, 0);
-
- /* Initialize LCD and LEDs */
- GUI_DispStringAt("Initializing lcd...", 0, 32);
- BSP_Config();
-
- GUI_Initialized = 1;
-
- /* Initialize RTC and Backup */
- GUI_DispStringAt("Initializing rtc and backup...", 0, 64);
- RTC_Init();
-
- /* Activate the use of memory device feature */
- WM_SetCreateFlags(WM_CF_MEMDEV);
- /* Do the calibration if needed */
- CALIBRATION_Check();
- }
