Request for STM32F103CBT6 ST-Link Schematic Review

hi

 

We are using the STM32F103CBT6 as the ST-Link controller in our new gateway board.

In the first version of the board, the ST-Link did not work as expected. We have made some changes, and this is the second version of the board.

Could you please review the ST-Link schematic section and let us know if there are any issues or recommended changes? Your feedback would be very helpful in ensuring that the ST-Link works correctly in this version.

Thank you in advance for your support.

Welcome ​@rogue76077, to the community!

The ST-LINK/V2 is not an open source tool, so officially you will neither be given confirmation that the hardware was functionally reproduced (illegally), nor that the firmware for it exists (closed source) or that the STM32 tools work with it. Please see the Terms of Use for further information.

If you want to use a fully functional and supported ST-LINK that can be soldered on, you should choose the STLINK-V3MODS.

Hope that helps?

Regards
/Peter

Hi,


Thank you for the clarification. We designed our board based on the ST-LINK section of the SOM Labs development board as a reference. We are not developing or reproducing the ST-LINK/V2 itself; we are using the development board design as a reference for our implementation.

Thank you for your suggestion regarding the STLINK-V3MODS.
