Ethernet dead when I use vTaskList

Hi all, When I use vTaskList(); in one task , my lwip task will not work . I just wrote the following : signed char taskbuffer[1024]    vTaskList(taskbuffer); and in FreeRTOSConfig.h : #define INCLUDE_vTaskPrioritySet        1 #define INCLUDE_uxTaskPriorityGet        1 #define INCLUDE_vTaskDelete            1 #define INCLUDE_vTaskCleanUpResources        0 #define INCLUDE_vTaskSuspend            1 #define INCLUDE_vTaskDelayUntil            1 #define INCLUDE_vTaskDelay            1 I just want to see all tasks status . Does anyone can tell me how to use vTaskList in application ?

This works for me: char taskbuffer[1024]; void DisplayTaskInfo (void) { ___vTaskList (taskbuffer); ___printf ( _________"______________Task_____Run_____Stack___TCBrn" _________"Task Name_____State__Priority__Free___Numberrn" _________"————__—–__——–__—–__——"); ___printf (taskbuffer); }

If you are having problems with just this function then most likely it is a stack overflow as this is the one place where sprintf() is used which can use a lot of stack depending on the implementation.  Check the amount of free stack and increase the stack allocated to the task calling vTaskList if needed.
