Problem flashing a card STM32WBA55G

Clemint

Hi, 

 

I have a STM32WBA55G card and I want to flash an example code but it doesn't work. So I used STM32Programmer to find out why my board wasn't "found". Normally STLink is included and I can go through the usb-c port. But I still get an error if I go through the uart connection: "Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... »

Et j’ai toujours l’erreur suivante si je passe par stlink : « Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication »

I can't find the solution, can you help me?

 

Best regards

Hi, I found the solution. I'm sorry for the inconvenience.

 

I checked every pin. And I noticed that the jumper was badly positioned on the JP5. Sorry for the inconvenience.

 

Kind regards

Hello @Clemint and welcome to the ST Community :smiling_face_with_smiling_eyes:.

Could you check the following point:
- The USB to micro used is a data transfer and not a simple charging cable?
- JP4 is in position on 5v_STLK? 

Best Regards.
