Debugging STM32Discovery with OpenOCD

Hello

I've sadly got to know that native ST-Link built in my STM32Discovery won't work with OpenOCD. So my question is: what hardware would you suggest to connect Discovery with to use OpenOCD? Some Jtag? First question should be: is it possible to do so?

TIA

Best Regards

Maciej

Yes it's possible

See here

Seems to defeat the point of having the debug hardware on the board.

You can always disconnect the SWD (CN3 jumpers, separate ST-LINK from STM32), and then wire up either your own SWD or JTAG connection to the STM32.

The schematic is here

Documents the connectors, and solder bridges, etc.

search for versaloon and here is a nice tutorial to use it:

OpenOCD not working with STM32Discovery, but exists stlink project, which fine working with STM32Discover.

https://github.com/texane/stlink

The newest version doesn't work for me though, try this one:

https://github.com/whitequark/stlink/commit/d1c3176f3a7cdbd7a0c4df832c627bc508a75296

It works:

For compile cut -Werror in build/Makefile,

add to gcc options

-Wl,--section-start=.text=0x8000000 \ #for load to flash

or

-Wl,--section-start=.text=0x20000000 \ #for load to SRAM

or change you ldscript

and read README.

This an old thread but still quite relevant.

OpenOCD does now support the stlink, both stlink/v1 and stlink/v2.

Board config's exist for all current discovery boards and standalone dongles.:

stm32f0discovery, stm32f4discovery, stm32ldiscovery, stm32vldiscovery.

Cheers

OpenOCD does not support SWD at all, at least up to now. So are at least my latest information.

Or am I wrong here ?

SWD is only supported in OpenOCD when using the stlink adapter.
