uC/OS-ii 移植到Atmeg128 编译环境为ICCV7 编译通过但是不能正常运行
下面是所有的代码，uC/OS移植好几天了，移植一直都不成功，哪位大侠给分析下，谢谢。所有的代码ourdev_545050.rar(文件大小:281K) (原文件名:myOS.rar) 移植函数有问题.

* INITIALIZE A TASK'S STACK
*
* Description: This function is called by either OSTaskCreate() or OSTaskCreateExt() to initialize the
* stack frame of the task being created. This function is highly processor specific.
*
* Arguments: task is a pointer to the task code
*
* p_arg is a pointer to a user supplied data area that will be passed to the task
* when the task first executes.
*
* ptos is a pointer to the top of stack. It is assumed that 'ptos' points to the
* highest valid address on the stack.
*
* opt specifies options that can be used to alter the behavior of OSTaskStkInit().
* (see uCOS_II.H for OS_TASK_OPT_???).
*
* Returns : Always returns the location of the new top-of-stack' once the processor registers have
* been placed on the stack in the proper order.
*
* Note(s) : Interrupts are enabled when your task starts executing. You can change this by setting the
* SREG to 0x00 instead. In this case, interrupts would be disabled upon task startup. The
* application code would be responsible for enabling interrupts at the beginning of the task
* code. You will need to modify OSTaskIdle() and OSTaskStat() so that they enable interrupts.
* Failure to do this will make your system crash!
*
* The AVR return stack is placed OS_TASK_HARD_STK_SIZE bytes before the bottom of the task's
* stack.
*
* (1) IMPORTANT: The ICC compiler handles function pointers by actually passing the pointer
* to a location in Flash that actually contains the pointer to the function.
