Hello everyone,

I have problem with my STM32F4 DISCOVERY board. According to spec:

+ Using ''Bootloader (USB FS Device in DFU mode)''

- Configure the STM32F4-Discovery board to boot from ''System Memory'' (boot pins BOOT0:1 / BOOT1:0)

- Set BOOT0 pin to high level: on the male header P2 place a jumper between

BOOT0 pin and VDD pin

- Set BOOT1(PB2) pin to low level: on the male header P1 place a jumper

between PB2 pin and GND pin       

- Connect a 'USB type A to Mini-B' cable between PC and USB connector CN1

to power the board.

- Connect a 'USB type A to Micro-B' cable between PC and USB connector CN5,

the board will be detected as USB device.

I did that steps, but I don't see ,,STM Device in DFU mode. I only see the ST-LINK in USB devices. Do you have any ideas where could be the problem?Thank you for your support,Mateusz #usb-dfu #stm32f429zit

The instruction are for a different board, not the STM32F429I-DISCO

The STM32F429I-DISCO connects the USB to the USB-HS rather than the USB-FS, the System Loader only supports the latter.

Thank you for your quick reply!

You're right, instruction is for different board. http://www.st.com/st-web-ui/static/active/cn/resource/technical/document/user_manual/DM00039084.pdf(Site 35)http://www.st.com/st-web-ui/static/active/cn/resource/technical/document/user_manual/DM00093903.pdf(Site 30)I was misunderstood by the fact, that in both documents (for STM32F4 DISCOVERY and STM32F429 DISCOVERY), the micro usb socket is connected to USB_OTG_FS. Is it mistake, or I understand it in wrong way?
