I've got it running on this board
http://www.mouser.com/ProductDetail/STMicroelectronics/STM32F4DISCOVERY/?qs=sGAEpiMZZMutVogd4PRSvEN8XDBeCtgD

See my c.l.a. post today on Ada on $15 hardware.

It's quite possible that the clock and enabling code is different for the different chip.  One thing that often gets forgotten with STM32 chips is that each GPIO port has a separate enable.  Have you set the enable for port G, in the proper register?

The code will look something like this:

   procedure Initialize is
      RCC_AHB1ENR_GPIOD : constant Word := 16#08#;
      RCC_AHB1ENR_GPIOE : constant Word := 16#10#;
   begin
      --  Enable clock for GPIO-D and GPIO-E
      RCC.AHB1ENR := RCC.AHB1ENR or RCC_AHB1ENR_GPIOD or RCC_AHB1ENR_GPIOE;

Do you have this code for GPIOG, using the correct RCC register?

Afterwards comes the configuration of the port bits:

      --  Configure PD12-15
      GPIOD.MODER   (12 .. 15) := (others => Mode_OUT);
      GPIOD.OTYPER  (12 .. 15) := (others => Type_PP);
      GPIOD.OSPEEDR (12 .. 15) := (others => Speed_100MHz);
      GPIOD.PUPDR   (12 .. 15) := (others => No_Pull);
      ....
