STM32U5A9J-DK demo board - odd display behaviour and Hard Faults

[Abon]

I recently received one of these demo boards and all worked as expected at first.  I wrote a simple TouchGfx app using MVP which worked fine.

A couple of weeks down the line and I started developing the app for which the board was purchased but I am seeing some very odd behaviour and the board is now almost unusable.

For example, a very basic application with just a background image from the stock collection and a button shows the wrong background image and the button isn't properly visible (pixelated).

If I try to debug the MVP app I wrote (and worked fine) a few weeks ago in the IDE it ends up in the HardFault_Handler() routine.

Is it possible the board is damaged?

I haven't changed any settings/jumpers on the board.

I am using TouchGfx designed version 4.22.0 to initially generate the code and STM32CubeIDE version 1.13.1 for debugging.

Hello @Abon ,

There is a chance that some mistakes happened and some faulty data is written to the flash. I suggest you erasing the flash memory using STM32CubeProgrammer. 
Please update us with the results.
