确认HSE_TIMEOUT_VALUE的值是否合适。如果超时值设置得太小，可能会导致程序在启动时等待外部时钟的过程...
调试发现,程序卡在if ((HAL_GetTick() - tickstart) > HSE_TIMEOUT_VALUE)处,不往下进行。原因:重复使能时钟。

} while((StartUpCounter != HSE_STARTUP_TIMEOUT) && (HSEStatus == RESET)); if (RCC_GetFlagStatus(RCC_FLAG_HSERDY) != RESET) { status = SUCCESS; } else { status = ERROR; } return (status); } 然后我们判断该返回值是否为SUCCESS,若是,则运行接下来的代码;若否,则使用if——else语句实...

This value, if non-null, will override values set by calling ServerSupportFunction with the HSE_REQ_IO_COMPLETION value set. pContext Points to an application-defined context structure that will be passed as a parameter by IIS when the asynchronous I/O callback function is called. hFile ...
The time between when the DRT senses a high on the MCLR/VPP pin, and when the MCLR/VPP pin (and VDD) actually reach their full value, is too long. In this situation, when the start-up timer times out, VDD has not reached the VDD (min) value and the chip is, therefore, not ...
