;* File Name : startup_stm32f10x_hd.s

;* Version : V3.5.0
;* Date : 11-March-2011
;* Description : STM32F10x High Density Devices vector table for MDK-ARM
;* toolchain.
;* This module performs:
;* - Set the initial SP
;* - Set the initial PC == Reset_Handler
;* - Set the vector table entries with the exceptions ISR address
;* - Configure the clock system and also configure the external
;* SRAM mounted on STM3210E-EVAL board to be used as data
;* memory (optional, to be enabled by user)
;* - Branches to __main in the C library (which eventually
;* calls main()).
;* After Reset the CortexM3 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

* The macro's crQUEUE_SEND_FROM_ISR() and crQUEUE_RECEIVE_FROM_ISR() are the

* This is the list implementation used by the scheduler. While it is tailored
* heavily for the schedulers needs, it is also available for use by
* application code.
*
* list_ts can only store pointers to list_item_ts. Each ListItem_t contains a
* numeric value (xItemValue). Most of the time the lists are sorted in
* descending item value order.
*
* Lists are created already containing one list item. The value of this
* item is the maximum possible that can be stored, it is therefore always at
* the end of the list and acts as a marker. The list member pxHead always
* points to this marker - even though it is at the tail of the list. This
* is because the tail contains a wrap back pointer to the true head of
* the list.
*
* In addition to it's value, each list item contains a pointer to the next
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
* and a pointer to back to the object that contains it. These later two
* pointers are included for efficiency of list manipulation. There is
* effectively a two way link between the object containing the list item and
* the list item itself.

If you find your application is crashing here then likely causes are
listed below. In addition see http://www.freertos.org/FAQHelp.html for
more tips, and ensure configASSERT() is defined!
http://www.freertos.org/a00110.html#configASSERT
1) Stack overflow -
see http://www.freertos.org/Stacks-and-stack-overflow-checking.html
2) Incorrect interrupt priority assignment, especially on Cortex-M
parts where numerically high priority values denote low actual
interrupt priorities, which can seem counter intuitive. See
http://www.freertos.org/RTOS-Cortex-M3-M4.html and the definition
of configMAX_SYSCALL_INTERRUPT_PRIORITY on
http://www.freertos.org/a00110.html
3) Calling an API function from within a critical section or when
the scheduler is suspended, or calling an API function that does
not end in "FromISR" from an interrupt.
4) Using a queue or semaphore before it has been initialised or
before the scheduler has been started (are interrupts firing
before vTaskStartScheduler() has been called?).

/*
* A sample implementation of pvPortMalloc() that allows the heap to be defined
* across multiple non-contigous blocks and combines (coalescences) adjacent
* memory blocks as they are freed.
*
* See heap_1.c, heap_2.c, heap_3.c and heap_4.c for alternative
* implementations, and the memory management pages of http://www.FreeRTOS.org
* for more information.
*
* Usage notes:
*
* vPortDefineHeapRegions() ***must*** be called before pvPortMalloc().
* pvPortMalloc() will be called if any task objects (tasks, queues, event
* groups, etc.) are created, therefore vPortDefineHeapRegions() ***must*** be
* called before any other objects are defined.
*
* vPortDefineHeapRegions() takes a single parameter. The parameter is an array
* of HeapRegion_t structures. HeapRegion_t is defined in portable.h as
*
* typedef struct HeapRegion
* {
* uint8_t *pucStartAddress; << Start address of a block of memory that will be part of the heap.
* size_t xSizeInBytes; << Size of the block of memory.
* } HeapRegion_t;
*
* The array is terminated using a NULL zero sized region definition, and the
* memory regions defined in the array ***must*** appear in address order from
* low address to high address. So the following is a valid example of how
* to use the function.
*
* HeapRegion_t xHeapRegions[] =
* {
* { ( uint8_t * ) 0x80000000UL, 0x10000 }, << Defines a block of 0x10000 bytes starting at address 0x80000000

* { NULL, 0 } << Terminates the array.
* };
*
* vPortDefineHeapRegions( xHeapRegions ); << Pass the array into vPortDefineHeapRegions().
*
* Note 0x80000000 is the lower address so appears in the array first.

There are two options for running FreeRTOS on ARM Cortex-M7 microcontrollers.
The best option depends on the revision of the ARM Cortex-M7 core in use. The
revision is specified by an 'r' number, and a 'p' number, so will look something
like 'r0p1'. Check the documentation for the microcontroller in use to find the
revision of the Cortex-M7 core used in that microcontroller. If in doubt, use
the FreeRTOS port provided specifically for r0p1 revisions, as that can be used
with all core revisions.
The first option is to use the ARM Cortex-M4F port, and the second option is to
use the Cortex-M7 r0p1 port - the latter containing a minor errata workaround.
If the revision of the ARM Cortex-M7 core is not r0p1 then either option can be
used, but it is recommended to use the FreeRTOS ARM Cortex-M4F port located in
the /FreeRTOS/Source/portable/RVDS/ARM_CM4F directory.
If the revision of the ARM Cortex-M7 core is r0p1 then use the FreeRTOS ARM
Cortex-M7 r0p1 port located in the /FreeRTOS/Source/portable/RVDS/ARM_CM7/r0p1
directory.

Each real time kernel port consists of three files that contain the core kernel
components and are common to every port, and one or more files that are
specific to a particular microcontroller and/or compiler.
+ The FreeRTOS/Source/Portable/MemMang directory contains the five sample
memory allocators as described on the http://www.FreeRTOS.org WEB site.
+ The other directories each contain files specific to a particular
microcontroller or compiler, where the directory name denotes the compiler
specific files the directory contains.
For example, if you are interested in the [compiler] port for the [architecture]
microcontroller, then the port specific files are contained in
FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the
only port you are interested in then all the other directories can be
ignored.

+ The FreeRTOS/Source directory contains the three files that are common to
every port - list.c, queue.c and tasks.c. The kernel is contained within these
three files. croutine.c implements the optional co-routine functionality - which
is normally only used on very memory limited systems.
+ The FreeRTOS/Source/Portable directory contains the files that are specific to
a particular microcontroller and or compiler.
+ The FreeRTOS/Source/include directory contains the real time kernel header
files.
See the readme file in the FreeRTOS/Source/Portable directory for more

EC20初始化流程：
1、IO初始化。
2、4G模块上电。等待上电完成，统计上电时间。 最多20S 。
3、网络参数初始化。
4、显示屏显示“设备入网中<EFBFBD> ”。
5、MCU与4G模块 AT握手，返回是否成功。
6、获取SIM卡状态，返回结果。
7、获取网络状态。
8、开启RF 。
9、获取CS Sever状态，返回结果。
10、获取PS Sever状态，返回结果。
