QuickStart reference for the GDB Server

Getting started with an GDB Server based JTAG solution

To use any of the GDB Server-based JTAG solutions available, you must configure the hardware and the software drivers involved. Currently the following GDB Server-based J-TAG solutions are available:

Using OpenOCD together with STR9-comStick

Follow these instructions to install and configure the OpenOCD (Open On-Chip Debugger) server:
  1. Download OpenOCD (eg. version 0.4.0) from http://sourceforge.net/projects/openocd/files/openocd. Documentation about OpenOCD is found at http://openocd.sourceforge.net/documentation.
    Extract the files to C:\openocd-0.4.0

  2. Download ftd2xx (CDM20802 WHQL Certified.zip) from http://www.ftdichip.com/Drivers/D2XX.html.
    Extract the files to C:\openocd-0.4.0\ftd2xx (This folder name is used by the configure command below)

  3. Insert the STR9-comStick device into a USB port on the PC. Windows will find the new hardware and ask for its driver. The USB driver is found in the ...\ARM\drivers\STComstickFTDI directory in your Embedded Workbench installation.

  4. Download and install Cygwin from http://www.cygwin.com/. Also select the additional GNU Make and GCC tools to be installed.

  5. Build the OpenOCD server
    Start the Cygwin command line window and do following:
    $ cd /cygdrive/c/openocd-0.4.0
    $ ./configure --enable-ft2232_ftd2xx --with-ftd2xx-win32-zipdir=ftd2xx
    $ make
    $ make install

  6. Start the OpenOCD server
    Do following in the Cygwin command line window:
    $ cd /usr/local/bin
    $ openocd.exe --file ../share/openocd/scripts/board/hitex_str9-comstick.cfg

  7. Start Embedded Workbench and open the USB demo example project for STR9-comStick usb.eww. The TCP/IP address to OpenOCD server is localhost with port 3333. This can be changed in the GDB server category in the project settings.

  8. Start the debug session and click on the button Run when download has finished. This application emulates a USB mouse. By connecting the secondary USB connector to a PC, the mouse pointer on the PC screen will start moving.
