Several tasks using same stack memory

[Lauris]

Hello everyone,

maybe anyone here is familiar with a way of making one stack memory for few tasks? Problem is that even if I'm defining one memory area for few tasks which runs for a short time and never runs at same time compiler makes few different allocations for them.

main.h
	//-----------------------------------------------------------------------
	static U64 stk_task		[1424/8];
	//-----------------------------------------------------------------------

file1.c
#include "main.h"
*
*
	taskID  = os_tsk_create_user (task, 0, &stk_task, sizeof(stk_task));	// Create Next Task
	os_evt_set (0x0001, taskID);

file2.c
#include "main.h"
*
*
	if (active_link.protocol) {
		taskID1 = os_tsk_create_user (task1, 0, &stk_task, sizeof(stk_task));
		os_evt_set (0x0001, taskID1);
	} else {
		taskID2 = os_tsk_create_user (task2, 0, &stk_task, sizeof(stk_task));
		os_evt_set (0x0001, taskID2);
	}


fragment of MAP file
    stk_Data_Send                            0x400051b8   Data        1424  file1.o(.bss)
*
*
    stk_Data_Send                            0x40005db0   Data        1424  file2.o(.bss)

Maybe I'm doing something wrong or missing something?
