Debugger tool

[HMTb]

Bonjour,

Je me permets de vous contacter afin de solliciter votre aide concernant le débogage d’une carte basée sur un microcontrôleur STM32L471 ( comme présenté dans les images suivantes ).

Je souhaiterais pouvoir programmer et récupérer les logs de la carte, et je cherche donc le matériel nécessaire pour cela (interface de debug, câble, connecteur et éventuellement sonde de programmation type ST-LINK).

Pourriez-vous s’il vous plaît me partager des liens ou références des produits compatibles recommandés pour ce type de carte ?

Je vous remercie par avance pour votre aide.

Cordialement,

Hello, I'm contacting you to request your help with debugging a board based on an STM32L471 microcontroller (as shown in the following images).

I would like to be able to program and retrieve the board's logs, and I'm therefore looking for the necessary equipment (debug interface, cable, connector, and possibly an ST-LINK type programming probe).

Could you please share any links or product references with me?…

Welcome to the forum.

Please see How to write your question to maximize your chances to find a solution for best results.

Please give some more details of this board: Is it your own design? Is it your own software? Schematics?

The STM32L471 supports both SWD and JTAG for programming/debug - so you'll need to determine which one is implemented on your board.

All ST-Links support both SWD and JTAG, and 3rd-party products are also available, such as J-Link:

Logs are entirely down to the software - so only you know what logs there are, and how they are intended to be retrieved.

For that, you really need to look at the documentation for the board, and/or contact its designer.

But it looks like this:

might be a 10-pin TagConnect; eg,

But you'd still need to verify that; eg, there might be a non-standard pin assignment.

PPS:

If you do get an ST-Link, be sure to get a genuine one:
