Hello ,
I recently purchased the STM32N6570-DK Discovery Kit. When I first powered it on, it showed a default video demo on the LCD along with live imaging, which I assume is the factory firmware.
Now, I would like to try some basic operations like UART communication and toggling an LED, so I created a new project for that.
Before flashing my custom code, I used STM32CubeProgrammer to read and save the default firmware as a .hex file from the board.
Before running my custom application, I wanted to restore the default original demo by reloading the saved .hex file. However, when I tried to program the board with this .hex file using STM32CubeProgrammer, it failed to load and showed an error (attached in the image).
So here are my questions:
Is it possible to directly reload the saved .hex file to get back the default factory demo?
Or do I need to generate a Project_trust .bin file with a proper secure header and flash that instead?
What is the correct method to restore the factory configuration and demo on this board?
Thank you in advance.
