E801(HwIOError): Invalid firmware - COM2:115200

[Pitt_Engineer]

I am currently having an issue with flashing my neural network (saved as a .tflite model) to my Nucleo-L476RG board. I am able to analyze the model successfully, but when I select, "Validate on Target", I receive the error message below: 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 - COM2:115200 

I have the following screenshots to show my STMCubeIDE as I attempt to validate on target: 

If someone knows how to fix this issue, please let me know.

Thank you! Validation on Target is working with what you suggested. 👍  But why cant I get accuracy. I am giving an npz file with windows and output. I am attaching the screenshot as well.

Hello !

Could you explain the steps you carried out . I am getting similar error for STM32F407G discovery board .

Hi,

I did the following steps:

Create a project in CubeMX with X CUBE AI and generate code for stmcubeide.

Import the project in Stmcube ide

Run the code on the target board.

Then open the .ioc file in the ide and Validate on Target. 

It worked for me.
