STM32F429ZIT6 program outside problem

[Sergen]

Hello, I bought STM32F429ZIT6 MCU the other day but strangely I am getting program outside error in the system and I have no hardware problem. So why is this happening? Is it a knock-off or a software problem

Hello @Sergen ,

If possible add more details to your post, so we could provide you better help about possibilities what could be wrong.

Check the power supply and connections that are stable and within the specified ranges, as this can cause programming errors.

You can also refer to the errata sheet for STM32F429 to check whether you have the limitation described for known issues that might cause programming errors.

You say there's not a HW issue but show a partial schematic.

You say there's an Error but don't show a screen shot or specify the error.

You say it might be a knock-off but don't show the device, its marking, or its source.
