WebJan 20, 2024 · 以STM32F4为例说明. TIM_ClockDivision：时钟分割,配置寄存器是TIM1->CR1. 共有3种分割参数，这里CK_INT是指选择的时钟时基见图1-紫红色. CK_INT是用户选择的内部时钟，比如通用定时器=84MHz（当预分频系数为0时），那么CK_INT=84MHz，若预分频系数不为0，则按照相关计算得出CK_INT大小；那么tDTS就可以对应计算了 Webu-boot的目的：启动内核内核的目的：启动应用程序，而应用程序位于根文件系统上面。因此，需要构建根文件系统。只需完成以上几步，就可以在单板上搭建出一个linux系统来。问题：有那么多应用程序，内核启动后首相打开哪一个？内核启动的时候，挂接好根文件系统之后，执行应用程序在init_post ...
