Hello, I have purchased Olimex’ SAM7-P256 board (with AT91SAM7S256) together with ARM-USB-OCD JTAG-Interface but I cannot flash the microcontroller. I have installed the toolchain from YAGARTO and used Jim Lynch’s very detailed manual, but for some reason it still doesn’t work. Using Jim’s example files (“demo\_at91sam7\_blink\_flash”), I can build the files for the uC, but as soon as I want to transfer the files into Flash-memory, the answer in the “console”-view is: make program Flash Programming with OpenOCD… 'C:\Programme\openocd-r247\bin'openocd-ftd2xx.exe -f 'C:\Programme\openocd-r247\bin'at91sam7s256-armusbocd-flash-program.cfg # program the onchip FLASH here /usr/bin/sh: C:\Programme\openocd-r247\bin\openocd-ftd2xx.exe: command not found make: \*\*\* [program] Error 127 It doesn’t matter if the board is actually connected to the PC or not, I always get the same response. Therefor I think the problem is somewhere in the toolchain setup rather than hardware. As you might have guessed from this description, I’m quite new to the whole “embedded systems” world. Therefore I assume my problem is hopefully nothing more than a beginner’s mistake. Any help is highly appreciated, chris P.S. I’m using the makefile and Open OCD-config files like available for download, therefore I didn’t attach them. If required, I can send them ---

Hello Chris, > /usr/bin/sh: C:\Programme\openocd-r247\bin\openocd-ftd2xx.exe: command not found The openocd-ftd2xx binary is not found. Have you installed OpenOCD on your PC? If not, take a look here: [http://www.yagarto.de/howto/openocd/index.html](http://www.yagarto.de/howto/openocd/index.html) Best regards, Michael ---

Hi Michael, thanks for the quick reply. I have installed OpenOCD right from the beginning, or at least I followed all the steps mentioned in your link. I also tested successfully the installation like suggested (with C:\make --version and C:\>openocd-pp -h), but I still get the same error. You mention that the openocd-ftd2xx binary is not found. What exactly is the name of the missing file? - openocd-ftd2xx.bin? I made a file search for openocd-ftd2xx.bin, nothing on my PC. And when I start OpenOCD as external tool from Eclipse, it works and I can see the according process in windows task manager. chris ---

Hello Chris, ```auto What exactly is the name of the missing file? - openocd-ftd2xx.bin? ``` It is openocd-ftd2xx.exe try to type in at your command: openocd-ftd2xx -h Regards, Michael ---

Hi michael, your command works, if I type in openocd-ftd2xx -h, i get the version number and a summary of all the commands i can use (-h, -f, -d, -l). But I still get “error 127” when I try to program my board… chris ---

Hi Michael, just to inform you that my problem is solved! Instead of using the standard-makefile code lines, I encoded the OpenOCD-parameters directly, so the program rule section looks like this: # program the AT91SAM7S256 internal flash memory program: $(TARGET) @echo “Flash Programming with OpenOCD…” #display a message on the console C:\Programme\openocd-r247\bin\openocd-ftd2xx.exe -f C:\Programme\openocd-r247\bin\at91sam7s256-armusbocd-flash-program.cfg # $(OPENOCD) -f $(OPENOCD\_CFG) # program the onchip FLASH here @echo “Flash Programming Finished.” # display a message on the console With this change flashing of uC worked perfectly. If I have time, I will check again where the difference between the original code line and my code line is, but that’s only low priority Once again, thanks for your suggestions, chris
