Hello,
I'm Henry from Siemens SI BP, working on the firmware platform, and we decided to use CMSIS-Driver (UART, I2C, SPI, etc.) as common hardware abstraction layer APIs.
Question: Do we have some where the CMSIS-Driver implementations as open source repositories (e.g. on GitHub). Then we could follow the latest update, report issues, and may make contribution as well.
Thank you!

Hello rkopsch,
Thanks a lot for your helping.
I knew this repository on GitHub which contains MCU independent (few common) device driver implementations and template files.
What I am looking for is the source of the vendor specific implementations for CMSIS-Driver, which you can find the full list here MDK5 Software Packs (keil.com). For example: "Keil.STM32F7xx_DFP.2.15.0.pack" contains many CMSIS-Driver implementations for STM32F7xx series.
Thank you very much and looking forward more hints from you :)
BR
Henry
Such ST Pack sources are not to find on GitHub, Henry.
I am not aware of any public device repo with CMSIS drivers.
Thanks for your feedback. For sure, I also didn't find any source of these implementations on GitHub.
The reason I'm asking the question here is that I believe somewhere in ARM Community might provide source code/repo of "device packs".
We have observed some issues in the current CMSIS-Driver implementations, and it would be great to access these open source repos where we can report issue, discuss solution, and even contribute with our enhancements (as normal open source projects).
FYI : I have seen the information in the header of device pack source code, like in the I2C_STM32F7xx.h:

I too, think the ARM Community would benefit from the Open Source Community. There's some stalled packs I would like to see updated, and don't mind doing it myself, except I can't find any repo to do so.
It's hard to understand why ARM would overlook such work horse, while wanting the biggest adoption. If ARM wants to control the merge or PRs, I don't mind one bit.
Nowadays opening to contributors seems like the way to go.
If anyone has contact names that could influence the decisions around this, I'd like to know them
Cheers
Thanks for this discussion and its ideas, which I have shared with the Arm Keil management.
In this specific case, I recommend also contacting ST(or any other SIP) to provide CMSIS-Driver support.
Hello Henry, In the CMSIS development branch, there's now an overview of known CMSIS-Driver implementations: (source for the table is here).Although, it currently doesn't include links to specific packs that contain the implementation, in most cases the drivers are provided either in the DFP for the target MCU, or in the CMSIS-Driver pack for external peripheral devices. We will see if actual links to the packs can be put there too.Should you find any gaps, feel free to let us know by raising an issue in the CMSIS GitHub repository.
