Maybe you need to use

adapter_khz 1000 ? Hard to know without your openocd.cfg and which board, jtag, etc. you're using...

STM32F3-Discovery, externalized ST-LINK, per previous interactions.

Dear clive1........

I am not using externalized  St-link instead i am using on-board st-link present in the discovery board. Also can you help me more on pin to pin connection of Stm32f3 discovery with external st-link debugger.

When i issue this command (after editing stm32fediscovery.conf file as you said by appending line:

adapter_khz 1000

) : sudo openocd -f /usr/local/share/openocd/scripts/board/stm32f3discovery.cfg I get following output:Open On-Chip Debugger 0.7.0 (2013-06-15-17:17) Licensed under GNU GPL v2 For bug reports, read     http://openocd.sourceforge.net/doc/doxygen/bugs.html srst_only separate srst_nogate srst_open_drain connect_deassert_srst adapter speed: 1000 kHz Info : This adapter doesn't support configurable speed Info : STLINK v2 JTAG v16 API v2 SWIM v0 VID 0x0483 PID 0x3748 Info : Target voltage: 2.909609 Info : stm32f3x.cpu: hardware has 6 breakpoints, 4 watchpoints I am using Ubuntu 12.04 and Openoocd (latest version)

I do not see any error in below output. Now what seems to be the problem?

Find what is adapter speed or just make it trail and error, but it does not seem like it would not be working.
