Error 200 and error 801 Validate on target on STM32F4291-DISCO

[LMart.12]

Hello,

I'm a newcomer in the STM32 machine learning world and I tried to make a AI model work on my STM32F429I-DISCO. Unfortunately the "Validate on target" option does not work... Errors are E200 and E801. Here is my thought process :

Iinstall a ftdi to my board to send data trough serial port : Then I launch stm32cube mx, select the board STM32F429I-DISC1 and start project without initialize all peripheral with their default mode. Then :

And finally :

I also tried validate on target on my other COM (COM4) and with communication port on the target : USART 1.

Each time I get the same result :

I don't know what to do, can someone know the solution of my problem ?

Thank in advance !

Best regards,

Martin

I write a quick program and visibly the communication is working both ways :

So the problem must be from X-Cube-AI or STM32CubeMX.
