Hello
friends, I am trying to make a dual core example on the Wio-E5 STM32WLE5JC Module. I made all the settings as in this video.  However, only CM4 works when debugging. CM0PLUS is not working and I am getting this error Target unknown error 32

Error in initializing ST-LINK device.
Reason: Unknown. Please check power and cabling to target. I tried this on STM32Cube ide 1.7.0 and 1.8.0.

Hello @FAlpa.1  and welcome to ST Community .

Wio-E5 is based on the STM32WLE5JC wish use just a single core ( Cortex-M4 ). you can't use it with a dual core application. I suggest you try an STM32WL5XXX for a dual core application.

I hope this is helpful.
