Can't send data through my board

Hello,

I'm trying to send data and retrieve the output from my stm32f4-DISCO. I'm using a python based code and specifically stm_ai_runner. The code is rather simpler but I can't access the board because even runner.summary() doesn't work. My board is flashed with the network :

It's the same as "validate on target" on CubeMx :

Running the STM AI c-model (AI RUNNER)...(name=network, mode=stm32)
 
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 - COM6:115200

So the problem must be from the board (It works on the H7) but I don't know why...

Hello,

Thank you for you response and your time.

I tried your method but I have the same "TimeoutError" as before. I don't think the problem come from the port COM that is already used because when I open the port COM via a terminal the error is :0693W00000QKvk0QAD.pngIt is a "access denied error" because windows can have only one process at a time accessing a COM port.

Best regards,
