Can the in-circiut STLINK on Nucleo board be used to debug STM8S?

I got a Nucleo F302R8 on hand, but now a STM8S003F3 is used on my project, i'm wondering if the STLINK on the Nucleo board can be used to debug the STM8S processor? and how should they be connected?

Any comments are appreciated!

Many thanks!

Hello Seven Zeng,

ST-Link embedded in Nucleo kits provide only SWD interface, which is compatible with STM32 MCUs, but it is not compatible with STM8 MCUs. SWIM interface, which is compatible with STM8 MCUs is not supported by ST-Link in Nucleo kits. So unfortunately you will be not able to use it with STM8S003F3.

Only Discovery kits and eval board with STM8 devices embed ST-Link, which supports SWIM interface for STM8 MCUs.

Standalone ST-Link supports all debug interfaces: SWD, SWIM and JTAG.
