stlink and OpenOCD
Spencer Oliver
I looked into adding support for the stlink to OpenOCD about a year
ago - never got around to finishing as it required quite a bit of
work.
Seems someone else has taken the 'bull by the horns' and added support.
It is still being reviewed on our gerrit server but feel free to
checkout/comment before we get this added to master repo.
Cheers

You you please give me a head start how to checkout/clone the code at zylin?
Thanks

No problem.
Checkout the OpenOCD code as normal:
git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd
the checkout the stlink patch (with configs)
git fetch http://openocd.zylin.com/p/openocd refs/changes/87/287/1 &&
git checkout FETCH_HEAD
build as normal
Here is my config - using STM32C-EVAL and STLINK-V2
set CPUTAPID 0x1ba01477
source [find interface/stlink-usb.cfg]
source [find target/stm32f2x_stlink.cfg]

make sure to use the --enable-stlink when calling OpenOCD configure, eg.
./configure --enable-maintainer-mode --enable-stlink
make
I have only tested under ubuntu using libusb-1.0

This bit all worked ok...

ahhhh, this bit could do with some work.... the git checkout has a README, that
refers to a non-existant INSTALL file. There's no configure... The developers
guide, at http://openocd.sourceforge.net/doc/doxygen/html/index.html has no
section on building. The users guide:
http://openocd.sourceforge.net/doc/html/Developers.html#Developers refers to the
README file...
Ok, let's try "bootstrap" ok, now we have a configure..... and can run make...
Ok, now what?

I don't get that far...
The documentation on where these damn .cfg files are located is pervese to say
the least. I resorted to "find" in the top level directory to look for them.
http://openocd.sourceforge.net/doc/html/Running.html#Running refers to the list
of search paths, but none of those names match any obvious directories in the
git package. Eventually, it seems that it's all underneath the tcl directory.

Now what? There's no "board" file I can see for any of the STM32 Discovery
boards, do I really need a board config to verify that I can talk to the programmer?
Later, I tried with the stm32f2x_stlink.cfg file, (I wasn't expecting to need a
different target config, I thought that was the point of the separation of
interface and target configs?) and it then _starts_, but commands like "reg"
don't do anything, nor does

I can't really say whether this is user error or patch error at this point.

INSTALL does exist.
As usual with Open Source projects some things may need tweaking -
patches are always welcome :)
The initial stlink support has been merged into master now so a simple
clone is required:
git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd
When building from git master then configure will need generating ...
./bootstrap
./configure --enable-maintainer-mode --enable-stlink
make
