OpenOCD w/ STM32

這篇文章是留給自己日後可以參考, 不要時間久了之後就忘了 XD

method 1 : openocd

compiling openocd. (link):

1. cd /tmp; git clone https://git.code.sf.net/p/openocd/code openocd
2. cd /tmp/openocd
3. 確定 libusb-dev 有安裝(使用環境為 Linux Mint 17.3 'Rosa') 後, 於 openocd 根目錄執行
   ./bootstrap
4. 因為僅需要使用到 STLink 所以組態僅指定 enable-stlink
   ./configure --prefix=/usr --enable-stlink
   跑完程式組態後, 最後可以概略知道 openocd 支援的功能清單:
   --------------------------------------------------
   OpenOCD configuration summary
   --------------------------------------------------
   MPSSE mode of FTDI based devices yes (auto)
   ST-Link JTAG Programmer yes TI ICDI JTAG Programmer yes (auto)
   Keil ULINK JTAG Programmer yes (auto)
   Altera USB-Blaster II Compatible yes (auto)
   Versaloon-Link JTAG Programmer yes (auto)
   OSBDM (JTAG only) Programmer yes (auto)
   eStick/opendous JTAG Programmer yes (auto)
   Andes JTAG Programmer yes (auto)
   USBProg JTAG Programmer yes (auto)
   Raisonance RLink JTAG Programmer yes (auto)
   Olimex ARM-JTAG-EW Programmer yes (auto)
   CMSIS-DAP Compliant Debugger no
   Altera USB-Blaster Compatible no
   ASIX Presto Adapter no
   OpenJTAG Adapter no
   SEGGER J-Link Programmer yes (auto)
5. 最後...
   make
6. 編譯完程式後, **不要安裝** 依據上面文章的建議, 在特定目錄建立 openocd 的程式目錄即可; 我是將其放在 ~/program/openocd 內
   cd /tmp/openocd
   mkdir ~/program/openocd
   cp -r tcl/* ~/program/openocd
   cp src/openocd ~/program/openocd
7. done!

Programming an STM32F103XXX with a generic "ST Link V2" programmer from Linux. (link)

先執行 openocd

~/program/openocd$ sudo ./openocd -f interface/stlink-v2.cfg -f board/stm32l4discovery.cfg
~/program/openocd$ sudo ./openocd -f interface/stlink-v2.cfg -f board/stm32f7discovery.cfg

連線至 openocd 作業

$ telnet localhost 4444
Trying 127.0.0.1...

測試過可以正常連線 STM32F767 & STM32L432; 有實際編譯 ChibiOS/RT 寫入 STM32L432.

method 2 : ST-Link

這個方式最為簡便 - 只需要購置 ST-Link or ST-Link/V2 再配合 stlink 即可.
