Hi,

What do you mean by “it does not like the config script” ? The openocd configuration script should be automatically generated for your target.

See in attachment, the config file generated for my NUCLEO-F411RE project.
Hope it helps.

Kevin.

Thanks, where does that file belong? I don’t see anything with names in capitals like that.

If I take the standard “automatic” feature it fails to connect. I found before if I searched out a config directly it worked but I think there is some more fiddling.

Hi,

I’ve renamed the file. It was generated in the project directory (as “Project_Name Debug.cfg”)

If you need to use an old config file “openocd/scripts/st_board/nucleo_f411re.cfg”, I think you have to add “-s PATH_TO_OPENOCD/openocd/scripts” (PATH_TO_OPENOCD to replace with the actual path) in the OpenOCD Options to indicate where to find the “target/stm32f4x_stlink.cfg” file.

Regards,

Kevin.

Thanks Kevin, that got me on the right path ( no pun intended ). I don’t recall using -s before but that did the trick.

OpenOCD Command:
${openstm32_openocd_path}/openocd -s ${openstm32_openocd_legacy_script_root_path}

configuration script:
${openstm32_openocd_legacy_script_root_path}/st_board/nucleo_f411re.cfg

Many thanks for the prompt help.

Oh, well the joy was short lived. Back to square one.

I restarted eclipse and goes back to the old behaviour even though the above settings are still shown. I actually don’t understand why auto config does not work, since yours apparently does. :?

Here is what is shown in the debug console when using automatic:
