STM32429I-EVAL1 getting started error: ST-Link is not in the DFU mode

Unlimit
Associate II

Hello, 

 

I'm trying to getting started with STm32429I-EVAL1 board with CubeIDE.

I coded a simple hello world program and built it, then I encountered error that "ST-Link is not in the DFU mode. Please restart it."

 

I did followings to solve it:

- restart the board

- unplug then plug the all cables (PSU, ST-Link V2, and USART)

- restart CubeIDE and rebuild the prohect

 

None of them worked, I don't know how to enter the DFU mode.

Also, I cannot find Port(COM&UPT) in the Windows device manager even I connected USART cable.

All the cables are connected into USB port on the PC.

 

Can anyone help me?

Hello,

No need to to but an ST-LINK as there is an embedded one on the board and you need to connect USB cable to CN21 connector.

Sorry I meant these two switches. They need to be at position 0 as following:

Also How you did configure the power supply? i.e. what about JP12 position?

You need to fit it at that position: "STlk":

And no need to connect the other cables as they are not needed for just to launch a debug session/program the board.

How did you connect the board to the PC?

This is the ST-LINK connector you need to connect to.

No need for DFU mode (bootloader over USB) as you are using ST-LINK.

What about Boot switch position? position 0?

I did nothing to boot position as following picture:

And I connected all of ports(ST-Link, PSU, and USART RS-232) to my PC.

Should I buy a new ST-Link? or can I do it without buying it?

Hello,

Now my board working well. I unplugged and plugged ST-Link cable before update.

Now all the board features seems okay.

But when I try to do USART transfer, I got some problem and I will open with new topic.

Thanks for your concern.
