Include the require Micrium software components* In the BSP setting dialog in the overview section of the left pane the following libraries* should be added to the BSP :** ucos_common* ucos_osii* ucos_standalone** 2. Kernel tick source - (Not required on the Zynq-7000 PS)* If a suitable timer is available in your FPGA design it can be used as the kernel tick source.* To do so, in the ucos section select a timer for the kernel_tick_src configuration option.** 3. STDOUT configuration* Output from the print() and UCOS_Print() functions can be redirected to a supported UART. In* the ucos_standalone section the stdout configuration will list the available UARTs.** Troubleshooting :* By default the Xilinx SDK may not have selected the Micrium drivers for the timer and UART.* If that is the case they must be manually selected in the drivers configuration section.** Finally make sure the FPGA is programmed before debugging.*** Remember that this example is provided for evaluation purposes only. Commercial development requires* a valid license from Micrium.**********************************************************************************************************//*********************************************************************************************************** INCLUDE FILES**********************************************************************************************************/#include #include #include #include ucos_ii.h#include LwipEnter.h/*********************************************************************************************************** LOCAL FUNCTION PROTOTYPES**********************************************************************************************************/OS_STK Polling_thread_Stk[256u];OS_STK LwipEnter_thread_Stk[512u];void MainTask (void *p_arg);void PollingTask (void *p_arg);/*********************************************************************************************************** main()** Description : Entry point for C code.***********************************************************************************************************/int main(){ UCOSStartup(MainTask); return 0;}/*********************************************************************************************************** MainTask()** Description : Startup task example code.** Returns : none.** Created by : main().**********************************************************************************************************/void MainTask (void *p_arg){ OS_CPU_SR cpu_sr; OS_ENTER_CRITICAL(); // Create Task OSTaskCreate(PollingTask, (void*)0, (OS_STK*)Polling_thread_Stk[255u], 20u); OSTaskCreate(LwipEnter_thread, (void*)0, (OS_STK*)LwipEnter_thread_Stk[511u], 50); OS_EXIT_CRITICAL(); // Suspend this Start Task after initialization OSTaskSuspend(OS_PRIO_SELF);}/*********************************************************************************************************** PollingTask()** Description : Polling task example code.** Returns : none.** Created by : MainTask().**********************************************************************************************************/void PollingTask (void *p_arg){ UCOS_Print (Hello world from the main task\r\n); while (DEF_TRUE) { OSTimeDlyHMSM(0, 0, 3, 0); UCOS_Print(Periodic output every 3 seconds from the main task\r\n); }}8、调试配置。调试配置如下图所示。9、启动调试。将测试PC机IP设置为192.168.1.99(与Zedboard处于同一网段)子网掩码为255.255.255.0。此时即可通过网口调试助手测试TCP的通讯功能。四、资源链接链接https://pan.baidu.com/s/1iVkFfXC964F7cCZVK8URCA提取码s5p1
