Hi Chris,
At ST level we are aware that the code should be public, that's why we are upstreaming our contributions into the official OpenOCD git.
For example the STM32WB support is here: http://openocd.zylin.com/#/c/4933/
but this change is not merged yet in the master branch.
Furthermore, we have a mirror of OpenOCD hosted here: git://git.ac6.fr/openocd
this mirror already contains the support of STM32WB in the branch named "st".
In the near future, we will host, another mirror into Github, representing the ST official fork of OpenOCD.
You can use the mirror above, until we prepare the Github mirror.
You will be notified once the Github mirror is ready.
Regards,
Tarek
