Second Controller STM32F1003 on Discovery board STM32F4x

Hi,

On the Disco board with STM23F4x there is a STM32F1003.

What is it there for, and how do I access it?

Thanks,

Johannes

I think there is a zero too much, it is a F103.

It is the embedded ST-Link.

Download and check the schematics in the user manual.

Hi Ozone, thanks for your time.

As you can see, I am rather inexperienced.

I looked over both data sheets , the STM32F407x and STM32F103, btw, you were right on that zero, I was Looking for any in circuit programming pin description, but could only find a boot0 pin.

On the Internet I found the explanation to that pin and boot1.

On the discovery STM32F4x the STM32F103 is part of a programmer?

I have only seen and worked with a programmer, that was connected to a miso mosi scl ICSPP pin on the chip, that I wanted to program, everything was already inside the programmer, for example the pic programmer, costed 30$.

Having a Bootloader is great, why would I want to spend money for a programmer if it has a bootloader? Is there any advantage ?
