What is the best way to debug I2C on 2 Nucleo Platforms (one Nucleo is Master the other Nucleo is Slave) while using ST CubeIDE?

[Micha Valach]

Hello,

I'd like to debug the I2C Master/Slave example located at:

..\STM32Cube\Repository\STM32Cube_FW_WB_V1.12.1\Projects\P-NUCLEO-WB55.Nucleo\Examples\I2C\I2C_TwoBoards_AdvComIT

I have the 2 Nucleo WB55 boards with proper I2C connection, And have a CubeIDE debug environment.

Is it possible to open both the Master and Slave projects running on different Nucleo platform simultaneously on the same ST Cube IDE? Is it similar for dual core debugging ?

Thanks In Advance,

Micha

Easiest is to open 2 STM32CubeIDE instances, one per project. In the Debug Configuration check the ST-LINK S/N box and scan for the correct ST-LINK adapter. This ensures that each project uses the same ST-LINK in all debug sessions.

Thanks a lot for your prompt response 🙂
