Why does STM32F4 Discovery kit

Hi,

I've just got a STM32F4 Discovery kit (STM32F429)

I thought that it embedded software for demonstate at the first time.

But my kit does not work.I also I read the below instruction.

But I don't know should I have to re-fund this kit?

What am I missing?

Getting started Follow the sequence below to configure the STM32F429 Discovery board and launch the DISCOVER application: 1. Ensure that the jumpers JP3 and CN4 are set to 'ON' (Discovery mode). 2. Connect the STM32F429 Discovery board to a PC using a USB cable type A/mini-B through the USB ST-LINK connector CN1, to power the board, the LEDs LD2 (PWR) and LD1 (COM). 3. The following applications are available on the screen: – Clock/Calendar and Game – Video Player and Image Browser (play videos and view images from the USB mass storage connected to CN6) – Performance monitor (watch the CPU load and run a graphical benchmark) – System Info 4. The demo software, as well as other software examples are available at the www.st.com/stm32f4-discovery webpage. 5. Develop applications starting from the examples.

Should just be able to plug in mini-USB cable and it should start.

Once you flash it with the ST-LINK/Keil you will remove the default program.

Cube should have an example you can rebuild and download.

Thanks Clive,

I found one of USB cables does not work. and I come across the board work as well when I re-connect with new cable.

I'd like to upload my GPIO simple test example firmware into my kit in Keil.

Does it make sense?

Could you let me know how do I upload my firmware? Is there any relative documents?

You select the ST-LINK as the debugger in Keil, along with the setting the flash algorithm to be that for the STM32F4 1 or 2MB, and then tell it to start debugging, by default it should download the code, and take you to the main() function.

Should I modify the jumpers status to upload the firmware? 

I want to know what am I supposed to do with JP1, JP2, JP3, and CN4.. when I want to upload the firmware and run the system.

The board should work exactly as shipped.
