uC/OS - III 移植 IAR平台

关于移植uC/OS-III 网上已经有很多教程了此处只是做个记录

首先下载源码然后解压得到下面的文件：

然后在模版工程里新建各种文件夹：

最后全部都添加进工程：

OK了，编译一下，惊呆了，竟然 0错误 0 警告

然后修改下文件 startup_stm32f40xx.s

        DCD     DebugMon_Handler          ; Debug Monitor Handler

        DCD     0                         ; Reserved

        ;DCD     PendSV_Handler            ; PendSV Handler

        ;DCD     SysTick_Handler           ; SysTick Handler

        IMPORT  OS_CPU_PendSVHandler

        DCD     OS_CPU_PendSVHandler

        IMPORT  OS_CPU_SysTickHandler

        DCD     OS_CPU_SysTickHandler
