Hi All,
I have two discovery boards. When I go into discovery mode (boot0 high, boot1 low) and then run ''dfu-util -l'' ... with one board I see the devices listed, the other board not .. could this be a faulty board?The ''good'' board was a fresh one just out of the packet. The one that doesn't work I have used before and was programmed via ST-LINK using openosd, that worked fine.But this time I want to use DFU and it does not work on that board. Is there a way I could have destroyed the bootloader with ST-LINK?Thanks, #stm32f4-discovery-dfu2015-07-17 03:54 PM

You'd want to check the supplies and regulators.
Check if the USB connector is viable, try a VCP or MSC example, of the FW Upgrade example if you have the right stubby cable to connect to a USB Flash drive.
