Onboard STLink-V2.1 on STM32MP157D-EV1 doesn't work

[Dub Bartolec]

Hi All,

We bought 3 STM32MP157D-EV1 boards (https://www.st.com/en/evaluation-tools/stm32mp157f-ev1.html)

While running in it as it is out of the box, we have found out that on-board STLink-V2.1 doesn't work at all when connected to Win11.

We've installed latest STM32CubeProgrammer and it actually installed latest STLink USB drivers (VCP and STLink) but despite all our efforts STLink doesn't work (LD06 doesn't glow) and Win11 Device Manager flags it as under error:

Is there solution to this issue ?

Hi,

I confirm board STLINK is running well on W11.

Did you have JP1 removed ?

Obvious, but please confirm you are using STM32MP157D-EV1 CN4 connector.

Did you try another cable ? Type-A <-> Micro-B is recommended.

Could you try an STLINK FW upgrade https://www.st.com/en/development-tools/stsw-link007.html 

Regards.

Hi @PatrickF 

I've confirmed...

• JP1 is inserted
• We are using CN4
• We tried several USB cables including one supplied with the board.
• We tried upgrade as you recommended and it never detects ST-Link. It needs to do that in order to upgrade it:
  
  
  
  No matter what we do we end up with this (all three board on 4+ different Win11 laptops and computers).
  
  

  Here is photo of board. LD6 is not illuminating at all.

  

  What would be next thing to try ?

[PatrickF · Accepted solution]

JP1 must be removed (otherwise it force the STLINK in reset in order to avoid conflict when using another debugger).

Probably a manufacturing issue when they setup default jumpers.

Hi @PatrickF 
Thanks STLink works now.
