After clicking validation ontarget, the following error appears:

E200(ValidationError): stm32: Unable to bind the STM AI runtime with “network” c-model: []

connection to “serial:115200″/”115200” run-time fails

E801(HwIOError): Invalid firmware – COM5:115200

This is because the cube AI toolkit of STM32 currently only supports a single core. If you use the stm32h747 dual core board, you can switch to the M7 core.
