Can someone help me understand an "invalid command name" error with openocd? Some details:

  • openocd 0.7.0 windows binary
  • olimex arm-usb-ocd-h dongle
  • lpc3250 phytec based board

Steps I've done:

  1. Downloaded file "openocd-0.7.0.7z" from http://www.freddiechopin.info/en/download/category/4-openocd
  2. Extracted it to "c:\oocd7\".
  3. Followed the instruction in "c:\oocd7\drivers\libusb-1.0drivers.txt" to run "sadig.exe" to install the "libusb-win32" drivers for the following three usb devices.
  4. Then got the error detailed below.

Command and Error Screenshot:

c:\oocd7>c:\oocd7\bin-x64\openocd-x64-0.7.0.exe -f board\phytec_lpc3250.cfg -f interface\olimex-arm-usb-ocd-h.cfg

Very much thanks to any comments!

    Have you tried reversing the order of the files? It appears that you need to place the interface file before the board file. [http://elinux.org/OpenOCD_Troubleshooting:_Invalid_Command_Name_JTAG] – Derek May 09 '13 at 01:52

    @Derek, That's correct. Can you put your comment into an answer? – minghua May 09 '13 at 16:53

You need to place the interface file before the board file.

Instead of:

> openocd -f board\phytec_lpc3250.cfg -f interface\olimex-arm-usb-ocd-h.cfg

You want :

> openocd -f interface\olimex-arm-usb-ocd-h.cfg -f board\phytec_lpc3250.cfg
