STM32 Nucleo not powering?
Hi,
I have just got a brand new STM32 Nucleo board,
now I just tried to power the board via the PC, simply plugging in the PC via USB, but
only the red LD1(COM) LED blinks, the others are OFF,
while on the manual I read "The red LED LD3 (PWR) and LD1 (COM)should light up. LD1 (COM) and green LED LD2 should blink"
Am I missing something obvious?
Thanks ISABEL

Have you tried to install the st link drivers: http://www.st.com/en/development-tools/st-link-v2.html
They also bring it up here, nucleo 64 board manual chapter 6.4: LEDS: http://www.st.com/content/ccc/resource/technical/document/user_manual/98/2e/fa/4b/e0/82/43/b7/DM00105823.pdf/files/DM00105823.pdf/jcr:content/translations/en.DM00105823.pdf
Such behavior does not indicate clearly that something is wrong with Nucleo. Nucleo behaves in the same way, for example, if it is connected to the USB charger or similar. If the Nucleo USB interface not carry the correct enumeration (connecting to driver on PC side), it will not turn on the power of the main processor (no flashing green LED) and flashing red LED. It is possible that it is still something wrong with the driver or USB cable.
You can check main procesor by close JP1 jumper (spare jumpers is on bottom side of Nucleo) and connect Nucleo to USB and see green led flashing. In my Nucleos it works. But this is not the solution to the main problem, only test.
Remember that if your Nucleo is brand new, firmware upgrade is needed, but without it, it should work properly.
