create new task in task?

Posted by vincent on July 20, 2012

I try to create A task in B task, FreeRTOS halt .

A task is created in B task
xTaskCreate(ssh_task,"SSH",configMINIMAL_STACK_SIZE*8,NULL, SSHSERVER_THREAD_PRIO, &sshhandle);

B task is created in main () function
xTaskCreate(serial_task,"COM", configMINIMAL_STACK_SIZE*4,NULL, COM_TASK_PRIO, NULL);

when B Task runing , i create A task , then system halt.
but I create A task in main() function, A task can work, and system don't halt .

anyone know why ?

Does the call to xTaskCreate() return? If so, what value does it return? Which memory allocation scheme are you using?

it return ePass, and the new task has run, but halt in task, i found that the code in task is long, so I spite them into different functions , now, it works ...so strange , it seems less memory
