I don't know what I can do after full chip erase

[aork]

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.

Hello,

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

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.

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?

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?

[SofLit]

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.

I'm stuck on the second step. How can I do this step with STM32CubeIDE? Could you give a little more detail? I'm really at a very beginner level and seem to be close to the solution. Can you help me a little more?

In order to make the program work, you must do the following :
 - Open your preferred toolchain 
 - Rebuild all files and load your image into target memory
 - Run the example

 I have read the instructions above but again stuck in the second step.

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:

Hope

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.
