Other Parts Discussed in Thread:SYSBIOS 0、使用simulator,原工程为单核运行裸跑在6678上,计划改成加载RTOS,8核并行; 1、已经根据实际情况自行添加了Repository; 2、添加CFG文件并启用TASK后能够编译通过; 3、TASK中添加Instance task0,并在main函数前添加: Void task0fun(UArg a0, UArg a1) { System_printf...
VxWorks的Task,也就是任务,是系统里最基本的执行单元,类似于其它操作系统的Thread(线程)。现代的RTOS基本都通过提供一个多任务环境来支撑上层的应用程序。而上层的应用程序则使用不同的任务来模拟真实世界里各种各样的分离事件。每个任务就是一个执行线程,使用着自己的系统资源。 那如果不使用多任务呢?也就是单任务...
配置UART1串口(但本例中不用到UART1): FreeRTOS配置 保存并生成基础工程代码: 在生成代码的这个部分可以看到FreeRTOS代码部分: 任务实现 基于前述的配置,main.c代码里会加载Free-RTOS的配置,并启动几个任务的调度,当然,此时的任务都是什么也不干。实现LED闪灯,就在LED闪灯任务里加入代码即可: voidStartTask_TASK_...

1、task stack size的使用率无法查看,只能看到task stack base adderss,如图1所示。2、虽然不可以看到task stack size的使用率,但是可以看到FLASH / GPRAM / SRAM的使用率,如图2所示。在CCS-view-memory allocation中可以查看。
