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:

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.
