5 1 Introduction This document describe how to integrate the Amontec JTAGkey-Tiny to use it on Development Kit SK- ERTEC 200 PN IO with ecos OS. There is no support on preconfigured GNU toolchains from Siemens side, please refere according suppliers: Amontec: Yagarto: The tools versions you download may differ, it is your challenge to modify settings suited. We recommend to use the same Version as described. Please see also chapter 5 Need-To-Knew/ Restrictions. 2 Necessary Hardware The Hardware Debugger can ordered under following address: Amontec, Gauch La Grand Fin Vuippens Switzerland Fax +41 (0) info@amnotec.com This Howto was tested with following Target Boards: Siemens Profinet Evaluation Board ERTEC Required Softwaretools This Howto requires that the SK- ERTEC 200 PN IO V3.1 with ecos OS is already installed. 3.1 Eclipse Version: You find Eclipse on the Development Kit CD in the subdirectory \tools\eclipse. It contains the version with all necessary plugins to work with the OpenOCD JTAG debugger. Eclipse could also be downloaded from eclipse website or other links. Be sure that the version you download includes the following plugins: Copyright Siemens AG All rights reserved. 5 Howto use Amontec JTAGkey-Tiny

6 CDT (C development toolkit) GDB Hardware Debugging If you use the following plugin CDT and GDB Hardware Degugging is included: CDT could be downloaded from eclipse -website or other links. If Eclipse is already installed you could check plugins by: Menu: Help About Eclipse Platform Plug-in Details 3.2 OpenOCD You find OpenOCD and the sources on the Development Kit CD in the subdirectory \tools\openocd. Sources of the OpenOCD could also be downloaded from the OpenOCD website or other links: We attached the configuration files for version LibUSB-Win32 Amontec JTAGkey-Tiny Driver You find a special driver and the sources for the Amontec JTAGkey- Tiny on the Development Kit CD in the subdirectory \tools\libusb-win32_ The driver and the sources of the libusb-win32 could be also downloaded from other websites: Don t use the current driver from the Amontec website. How to install the libusb-win32 driver and how to verify the installation, you can find in the corresponding txt documentation, which is also downloadable from this website. 3.4 GDB A suitable ARM gdb must be referenced in the eclipse Debug configuration. After installation of the development kit CD it is located in the following folder: PNIODevKit3/msys/1.0/local/bin/arm-ecos-elf-gdb.exe 4 Integration of Amontec JTAGkey-Tiny 4.1 Step 1 Unpack Eclipse Unpack Eclipse into a user defined folder, e.g. D:\eclipse. Start eclipse by double clicking on file eclipse.exe and set workspace to the folder required by SK- ERTEC 200 PN IO (e.g. C:\PNIODevkit3 ). 4.2 Step 2 install Eclipse plugin This step can be skipped, if Eclipse is installed from the PROFINET IO Devkit CD. In this case all necessary plugins are already installed. Copyright Siemens AG All rights reserved. 6 Howto use Amontec JTAGkey-Tiny

7 Plugin s have to be installed by using Eclipse install process. We suppose following: 1) Unzip the downloaded plugin package described under 3.1 2) Add package to Available Software under Eclipse by Menu: Help Software Updates and Addons Availabel Software Add Side, choose Local and browse to the package described above. 3) The package should now be available in the Available Software window, you could install it by highlight it and pressing the left mouse button and select Install. 4.3 Step 3 Install the LibUSB-Win32 Amontec JTAGkey-Tiny Driver Install special driver and software provided by Amontec JTAGkey-Tiny Hardware debugger, take care on the install procedure, because you have to select the device by list and browse to the install folder. To verify the installation, start the device manager with start system system hardware device manager. If everything is correct, you find under LibUSB-Win32 Devices the AmontecJTAGkey (Channel A) and AmontecJTAGkey(ChannelB), see the following screenshot. 4.4 Step 4 Install and start OpenOCD 1) Install OpenOCD 2) Connect JTAGkey-Tiny and powerup Ebx00 Board 3) Go to folder..\pniodevit3\openocd. 4) Execute Batchfile StartOcd200Debug.bat. This batch starts openocd with the correct parameters. OpenOCD version 0.2.0: The batch starts OpenOCD by: openocd -f eb200_debug.cfg c init c reset Note: it is possible to set a different location path <anypath>\eb200_debug.cfg, if this file is located in a different directory. Copyright Siemens AG All rights reserved. 7 Howto use Amontec JTAGkey-Tiny

8 Following should be displayed (version 0.2.0): Note: OpenOCD must run simultaneously with Eclipse for debugging. 5) Check OpenOCD is running by open an telnet connection,execute following on command window: telnet localhost The Following should be displayed (version 0.2.0): This is just to check if openocd is running is not necessary for debugging by Eclipse/ gdb. By typing help you will get a list of all available functions (read/ write memory, read/write register, flash programming). 4.5 Step 5 Configure Eclipse 1) Run Eclipse 2) Generate Debug Configuration, by Menu Run Debug Configurations... Copyright Siemens AG All rights reserved. 8 Howto use Amontec JTAGkey-Tiny

9 3) Select GDB Hardware Debugging and generate a new configuration by press the New button 4) On the Main site make following settings: Copyright Siemens AG All rights reserved. 9 Howto use Amontec JTAGkey-Tiny

10 5) On Debugger site check following settings and set path to ARM gdb: Copyright Siemens AG All rights reserved. 10 Howto use Amontec JTAGkey-Tiny

11 Note: A suitable ARM gdb could found on the SK- ERTEC 200 PN IO in folder: PNIODevKit3/msys/1.0/local/bin/arm-ecos-elf-gdb.exe 6) On Startup site make following settings: Copyright Siemens AG All rights reserved. 11 Howto use Amontec JTAGkey-Tiny

12 Note: The command monitor reset init is passed via gdb to the OpenOCD monitor and execute the reset-init sequence specified in the configuration file. load fore the gdb to load the elf file via OpenOCD to the target. Note: Enable resume will start application immediately after download. 7) Save modification on press Apply button 8) Compile your system (ecos and PNIO Application) as mention in DevKit manual 9) Run Debugger by Menu Run Debug or shortcut or press F11, elf file will be downloaded and debugger stopps at reset_vector. Now you could add a breakpoint and start debugging. Note: OpenOCD must run. Note: If there is now breakpoint set, the SW will be downloaded and started.

13 4.6 Step 6 Write a new executable image into flash With the OpenOCD JTAG debugger you can write the executable image ecos.bin (not PNIO4ECOS, that is the image for the jtag debugger, starting from ram) into flash eprom. This image starts after power on or pressing the reset-button on the EB200. To flash the image, do the following steps: 1) copy the file to flash (ecos.bin) into the folder..\pniodevkit3\openocd. 2) Open folder OpenOcd 3) Execute Batchfile StartOcd200Flash.bat The following window occurs: 4) Open a telnet console by executing the batchfile StartTelnet.bat. This batch executes the following command: telnet localhost The following window occurs: Copyright Siemens AG All rights reserved. 13 Howto use Amontec JTAGkey-Tiny

14 5) Execute the following commands in the telnet console. You can do this either by hand with the keyboard or copy the complete sequence from the textfile flash_telnet.txt into the clipboard and paste it with a right mouseclick into the telnet console. In this case the whole sequence is executed automatically (recommended way). Copyright Siemens AG All rights reserved. 14 Howto use Amontec JTAGkey-Tiny

16 6 Need-To-Knew/ Restrictions 1) This Howto is based on Siemens Profinet SK- ERTEC 200 PN IO V3.1. 2) OpenOCD recommend to disable MMU, MPU and Cache for debugging. The actual configurations script s doesn t disable this functions, therefore ist isn t possible to set Software Breakpoints. 3) On ERTEC200 are two Hardware Breakpoints available. If single step debugging is selected, then just one Hardware Breakpoint is available, the other one is for stepping necessary. 4) In the current version no Working Area is defined, test shows that downloadspeed will double. 5) The debug performance will decrease if several variables are under oberservation. 6) Sporadically error messages may occur during flash erasing or flash writing. Anyhow Firmware may still be flashed correctly. If flashing fails, please try again. If problems replicate, we recommend to use another debugger. 7 Annex 7.1 openocd Version Configuration File for debugging on EB200 You find the configuration in the folder d:\pniodevkit3\openocd\eb200_debug.cfg. 7.2 openocd Version Configuration File for firmware flashing on EB200 You find the configuration in the folder d:\pniodevkit3\openocd\eb200_flash.cfg.
