I did not know that, switching to dap interface got more output, but still an

**[tickets:#398] Status of STM fork and adding support for new STM32 silicon**
**Status:** new
**Milestone:** 0.11.0
**Created:** Wed May 31, 2023 11:05 AM UTC by Jan Henke
**Last Updated:** Wed May 31, 2023 02:44 PM UTC
**Owner:** nobody
Hi,
I have purchased a STM32WBA52CG nucelo board and noticed OpenOCD does not yet
has support for these newer chips STM released in the last months (they
released several new series).
I stumbled across a fork of OpenOCD created by STM:
https://github.com/STMicroelectronics/OpenOCD
They have added support for the STM32WBA family to that fork's flash driver
along with some other of the new chips (but unfortunately no target config file
yet).
So I have two questions:
1. What is the status of that fork? Was there any discussion between STM32 and
the OpenOCD project in that regard? With OpenOCD being GPL-2 licenced I would
assume it is no problem to just cherry picks the relevant commits from that
fork back to main OpenOCD?
2. I am struggling with creating a working target config file for the STM32WBA
chip. The support was added to the STM32L4x flash driver (which already
supports several STM32 families). Is it enough to copy the existing STM32l4x
target config and updating the JTAG and SWD values with the correct ones from
the STM32WBA reference manual?
Best regards
Jan Henke
