How to debug the Seeed Studio AI Assistant board using a STLink/V2 debugger

Hello,

We have bought the new AI Assistant board from Seeed Studio and we need some help on how we can connect an external debugger.

We have two STLink/V2 debuggers, the plain and the ISOL version. However with the cables that they have we cannot connect any of them to the 8-pin debug port of the Seeed board.

We assume that the necessary pins are on the STM32 connector, but which are they? Additionally the picture of the STLink/V2 debugger in:

https://wiki.seeedstudio.com/ai_assistant_getting_started/#additional-documentation-of-the-application

does not correspond to the debugger we have. Is that a different board from the one we have?

Thanks in advance

    First of all thanks for the reply. It is good to know the support options of Seeed Studio.

    I wrote here because in the end of

    https://wiki.seeedstudio.com/ai_assistant_getting_started/#resources

    it clearly says that the product is supported by STMicroelectronics.

    Also in the photo with the pinout next to ST-Link V3 it also has an image that says ST-Link V2.

    However I found the solution searching the STMicroelectronics site. I found the technical note TN1235 "Overview of ST-LINK derivatives" and I understood that the photo in the Seeed site actually corresponds to the ST-Link V2-1 version that includes the Uart pins. The plain ST-Link V2 debuggers do not have the Uart pins. 

    So finally with a Nucleo board as in the photo I managed to connect with the board. 

    Thanks again

    As it's a Seeed Studio board, you should be going to Seeed Studio for support:

    https://aftersale.seeedstudio.com/home 

    https://forum.seeedstudio.com/

    https://discord.com/invite/QqMgVwHT3X

     

    Particularly as it's a new product, you need to feeding back to them on needed improvements!

    That really is a question for Seeed Studio!

    But the schematics are on the page you linked:

    As it says in the picture, that's an ST-Link V3:
