Incorrect peripherals

[Admsher]

I am using a STM32 F4 discovery and using this crate I was trying to use the blinky.rs for the same board but the pin seems to be different form what is given in the example ( for me it is gpioc.p0) , moreover the led only turns high and doesn't blink.

Too few information and many potential reasons to fail.
What discovery board are you using? (ideally link to documentation).
Does RCC initialization finish correctly?

The boar I am using is STM32F407VGTx and i am using the direct example. The code does compile so I guess the initialization does happen correctly.
