STM32F407G-DISC1 - Issue with DFU mode

[BAW]

Hello,

I am new to STM products. I have a STM32F407G-DISC1 board and would like to demo a flash program update over USB. I am using the STM32CubeProgrammer.

I am using the following to set up the board for DFU: STM32F407G-DISC1/STM32F4DISCOVERY DFU mode · GitHub

Below is a picture of the board with the connections:

When I open the STM32CubeProgrammer it shows DFU not detected.

Any insight as to what I am doing wrong?

Thanks,

Brent

Check NRST solder bridge between ST-LINK and F407 is disconnected.

Perhaps also power the North USB connector, you want the 8 MHz MCO clock from the ST-LINK for the F4 USB to function

Hello @BAW ,

Could you please refer to How can I use STM32CubeProgrammer to access the US... - STMicroelectronics Community  and check your hardware connection.

I hope this help you to solve the issue.

Thank you.

Thank you both for the information and suggestions.

Looking in the AN2606 Application note, I needed Pattern 1 to activate the bootloader. 

I needed to pull Boot1 to ground. Before I was only jumping Boot0 to VCC.

Thanks again for the help.
