STM32CubeAI: INTERNAL ERROR: E801(HwIOError): Invalid firmware

[knight]

Dear Community,

I am attempting to deploy an .onnx model to STM32F407VET6 via STM32CubeAI 10.0.0.

I have generated the code, completed the compilation and download through MDK5, and also completed the validate on desktop on STM32CubeMX. However, when conducting the validate on target, I encountered the "INTERNAL ERROR: E801(HwIOError): Invalid firmware - COM3:115200" issue. I'm a novice, maybe I haven't done the configuration work well and don't know how to make adjustments.

I have attached my code file in the attachment. If I need to provide more relevant files, please let me know. I would be extremely grateful!

Regards

Hello @knight,

To do a validation target with X Cube AI:

• Make sure to use the lastest available version of X Cube AI
• Open CubeMX and select your board

• Initialize all peripherals as default
• Look for X Cube AI under Middleware and Software Packs
• Activate X Cube AI and select the validation template

• Browse for your model
• Make sure that the model is compatible by doing an Analysis
• Click on Validation on Target
• Com Port: Automatic, Baudrate: 115200 (921600 for N6)
• Check Automatic Compilation and Download
• Select your toolchain / IDE: STM32CubeIDE
• Make sure that your board is connected to the PC

Then, to create your own application, use the application template instead of the validation template

Have a good day,

Julian

Dear Julian,

Thanks for the guideline! I followed your steps, successfully generated code in STM32CubeMX, built and run project in STM32CubeIDE, but when I tried to validate on target again, there is a "No board connected on the machine with MCU" issue. Do you know how to fix it? Thanks a lot again.

Dear Knight,

In order to perform validation on target you need connection to MCU UART via ST-Link Virtual COM Port (VCP) to exchange validation data with PC e.g. on NUCLEO board such a connection is implemented. I'm not sure what kind of STM32F407 board you are using (proprietary one ?), please make sure you have such a connection and ST-Link is capable to provide VCP profile (>= ST-Link v2.1). As reference you can see NUCLEO-F429 -> USART3 pins PD8, PD9 are connected to on-board ST-Link VCP.

Best regards,

Bartosz
