在system_init函数中我们可以找到上述代码,浏览该文件我们可以知道,timer_irq_handler即系统定时器的中断入口函数, 在原有FreeRTOS工程中该函数内容如下: void timer_irq_handler(uint32_t mcause) { #warning requires critical section if interrupt nesting is used. if (xTaskIncrementTick() != 0) { vTask...

1voidtimer_irq_handler(uint32_tmcause)2{3#warningrequirescriticalsectionifinterruptnestingisused.4if(xTaskIncrementTick()!=0){5vTaskSwitchContext();6}7} 该函数实现系统节拍的产生,所以将这里的内容修改为RT-Thread的节拍产生的方式,修改如下:
void timer_irq_handler(uint32_t mcause) { #warning requires critical section if interrupt nesting is used. rt_interrupt_enter(); rt_tick_increase(); rt_interrupt_leaves(); } 涉及到中断,我们就得考虑系统的中断的实现方式,中断一般会分为向量中断与非向量中断。RISC-V常在启动后文件中进行中断模式...
