Hello everybody,

I have a problem with the STM32F107 bootloader. I have a ST32F107 chip monted on a keil MCBSTM32C evaluation board. When I activate the bootloader by placing the boot switchs to select System memory as the boot space, I’m able to download my application via the UART. But in USB when I launch DfuSe Demo, my device is not recognised by the PC, so it not appears in the Available DFU and compatible HID device. I don’t understand what I’m doing wrong. Anyone have already have this problem and can help me to solve it ??

Hi, check and post the date code, on older eval boards are MCUs without USB bootloader. If it's your problem, ask your sales channel for replacement of the board or MCU.

Hi Edison,

Thanks for your reply. I check my date code, it's 961.

961 is a test series (61 is bigger than week number in '09). Replace with something bigger than 937.
