Hi, I have a STM32F407 Discovery Board and I'have made full cihp erase. But I have no idea what I can do after doing this. In the communtiy I have read that I have to install the original firmware. How can I do that? Can you help me? Thanks from now.

    Go to STM32CubeIDE folder and double click on .project file.

    This window will be shown, click "Launch" button:

    and wait until the project workspace is loaded. You have to get this view:

    Then click on the "Hummer" button to build the project. When it was completed,

    Click on the arrow button shown in red and go to the menu shown below:

    If this window is shown, click OK button to load the program to your MCU target and launch the debug session:

    To run the program click on this button:

    To stop the debug session click on this button:

    Hope it helps.

    Hello,

    Not clear what do you want to do after doing a chip erase, programming a specific application? which one?

    Actually I don't know what to do either. I just wiped the chip. I am a completely new user and I want to tackle very simple projects. After erasing the chip, I want to use it as I first purchased it. So basically, I don't know what would happen if completely erasing the chip. Do I need to do anything after erasing the chip? If so, how should I do it? Would you help me with this topic?

    The picture looks good. Have you excluded all possible errors on your side? E.g.

    - 5V on non tolarant pins?

    - Dangerous external voltage applied before or after proper MC voltages reached ?

    Last errors have resulted in chips with high current consumption, partly still functional.

    No, I just clicked on Full Chip Erase using STM32CubeProgrammer and that's it. Can I use the card afterwards? I don't know. I'm looking for help on this matter

    Hello,

    Download the firmware package of STM32F4 from here.

    and go to the simplest example toggling a LED by user button: https://github.com/STMicroelectronics/STM32CubeF4/tree/master/Projects/STM32F4-Discovery/Examples/GPIO/GPIO_EXTI

    Use STM32CubeIDE to compile the project and load the program to your board.

    As you are a newbie with STM32, I recommend you to read this wiki.

    Do I need to install or install these files that I downloaded? What path will I follow?

    What do you mean by "install these files"?

    You need to:

    - Dwnload the package I provided previously.

    - Download STM32CubeIDE toolchain and compile one of the examples.

    - Program your board by the compiled example.

    You need to read the wiki link.

    Attached a complete project from which you can try the example.

    Go to F4_Discovery_Example\Projects\STM32F4-Discovery\Examples\GPIO\GPIO_EXTI\STM32CubeIDE

    If it doesn't compile, unzip the folder under your root drive C:

    First of all, thank you very much for your interest, but when I click on the Debug section, this appears and it seems like it is not normal. I did what you wrote step by step. What should I do? I'm so desperate
