Just got my STM32F4-DISCOVERY from ebay.com, was having hard time to work with.
Since i've plugged the USB mini cable to the board and my laptop. I've managed the CN3
jumpers are ON. The LED LD1 or the COM led was blinking the shinny yellow light.
Curious... ahah! Just found that my USB mini cable is not a data cable but a power cable
that bundled with my portable USB Powerbank.
