stack pointing wrong?

Posted by Steven on September 6, 2010

hey all,

i have made a basic task scheduler with some elements of the RTOS system
for example i use the same SAVE_CONTEXT and RESTORE_CONTEXT and initialise stack

this is my main:

//main includes
#include "Main.h"
#include "Config.h"
#include "Scheduler.h"

//task includes
#include "KnipperLed.h"

/*
 * Create task and then start scheduler
 */
void main()
{
createTask(knipperLed, 5);//(address task, priority)

startScheduler();
//here prog never comes
}

but i have one problem: if the scheduler starts, the stack points to
the createTask from my main routine instead of to the task?

how is that possible with the same initialise stack and restore_context?
