查了一些相關網站，似乎因為ST-LINK更新，導致我的STM32F407無法從SWV ITM Data Console看到printf的資料，建議適用SEEGER來查看~

使用SEGGER作為追蹤工具

下載列表

1. SEGGER SystemView Software -> 下載到HOST上
2. SEGGER SystemView target source files -> 放到FreeRTOS中並整合進開發版上
3. SEGGER ST-Link Reflash utility -> 本次不使用(如果要用3就要一併用4)
4. SEGGER J-Link software package V5.12b or later -> 本次不使用
5. SystemView user manual 用戶手冊

講師的建議是使用更新版本的FreeRTOSv11跟SystemView Target Source v3.54，這樣未來才不需要使用Patch file並導致其他的錯誤(os. 看來要全部重來一遍了)
SEGGER SystemView Software & System Target source files download v3.20 version:

下載SEGGER SystemView Software到主機上:

記得要勾選install a new instance:

簡單介紹介面:

右上角選File->Load Data->C:\Program Files\SEGGER\SystemView_V320\Sample->選OS_IP_WebServer.SVDat，我們Load 範例來介紹一下SEGGER的介面

1. 紀錄所有與Target相關事件的時間、名稱、詳細資訊等_可以拉下所有事件來看，其實這紀錄了這10秒鐘發生的事件
   
2. 點選Windows-> Timeline
   
   紅色表示該Systick使用的時間，灰色代表進入Scheluder，藍色代表這個task運行的時間
3. 點選Windows-> CPU Load & Windows-> Contexts
   可以看到CPU Total Run Time 近10秒，就了解到其實CPU大部分時間都在idle
   
4. 點選Windows-> Treminal
   可以從Terminal看到相對應的Task事件
   

將SEGGER System應用到Project上

Step1: Adding SEGGER SystemView target sources to the project

• Download SystemView target sources and extract it
• Create the folders
  (1) ThirdParty下建立名為"SEGGER"的資料夾
  (2) 在"SEGGER"資料夾下建立四個資料夾"Config"、"OS"、"Patch"、"SEGGER"
  Config資料夾要有:
  前三個檔案來自SystemView_Src_V320\Config
  最後一個來自SystemView_Src_V320\Sample\FreeRTOSV10\Config\Cortex-M
  複製貼上至Config資料夾
  
  OS資料夾要有:
  這兩個檔案來自SystemView_Src_V320\Sample\FreeRTOSV10
  
  Patch資料夾要有:
  來自課程提供:
  p.s 如果使用的FreeRTOS版本為v11(up)且SystemView版本為v3.54(up)就不用Patch
  
  SEGGER(最內層的)資料夾要有:
  檔案來自SystemView_Src_V320\SEGGER，全部複製貼上即可
  
  因為不會用到其他編譯方式，所以SEEGGER\Syscalls裡面僅保留GCC即可
  

Step2: Patching FreeRTOS files

you need to patch some of the FreeRTOS files with patch given.

1. 確保ThirdParty\SEGGER NOT check exclude resource from build
   
2. 添加Patch文件
   發生error!
   講師的建議是使用更新版本的FreeRTOSv11跟SystemView Target Source v3.54...

SEGGER SystemView?

SystemView is a software toolkit which is used to analyze the embedded software behavior running on your target.
The embedded software may contain embedded OS or RTOS or it could be non-OS based application.
SEGGER SystemView Toolkin come in 2 parts, (1) PC visualization softwar: SystemView Host Software(Windows/Linux/Mac), (2) SystemView target codes (this is used to collect the target events and sending back to PC visualization software)
System Visualization modes:

1. Real Time recording (Continuous Recording):
   With a SEGGER J-Link and its Real Time Transfer(RTT) technology SystemView can continuously record data, and analyze and visualize it in real time.
   Real Time mode can be achieved via ST-link instead of J-Link. For that J-Link firmware has to be flashed on ST-Link circuitry of STM32 boards.
2. Single-shot recording:
   You don't need to have J-Link or ST-Link Debugger for this.
   In Single-shot mode the recording is started manually in the application, which allows recording only specific parts, which are of interest.

因為要重新下載FreeRTOSv11跟SystemView v3.54，所以全部Code & Project要重來一遍，所以進度暫停，明天繼續往下走，先去重新安裝所有東西
