緣起

前一陣子知道 Intel 出 MCU, 這這這是怎麼回事，超級好奇以 Intel 這樣超高技術與製程能力，會是做出什麼樣的 MCU? 一直沒在 MCU 市場琢磨的 Intel, 做的 MCU 能看嗎？

 

由於機緣，入手了一台，想說研究一下，看看到底是個什麼樣的東西

 

循著網站步驟，安裝完軟體，不用 ICE，就可以使用在 Eclipse 下中斷，Debug

仔細一看，板子開源， Debugger tool, IDE, 韌體全開源, SDK/Sample code 也全部開放，再加上 Intel 的文件與品質與 NT 533 的入手價格

 

這一定得好好研究透徹啊，搞清楚其中所有環節，保證讓你功力提昇一甲子

 

哈爸自己也已經研究了好幾天了，還是很多部份實在不懂，於是想跟大家一起共學，大家一同研究，透過一同研究，彼此分享學習，順便交交朋友

 

共學方式

  • 意願表達即可加入
  • 會加入一個臉書串
  • 在此共筆研究心得
  • 另找時間在 StarFab（清大育成中心） 聚會討論

會議記錄：

 

研究筆記

  • Upgrade ROM by command line base

Open Command Window :

cd IntelSWTools/ISSM_2016.0.0XX

issm_env.bat

cd %ISSM_DEBUGGER_ROOT%/openocd

bin\openocd -f scripts/board/quark_d2000_onboard.cfg

=> OCD already open or attach to GDB

On a new window (or use a Terminal Emulator) open a telnet connection to OpenOCD :

telnet localhost 4444
