Im using the stm32f407vg discovery board, and coocox is my ide.
Im trying to use  Random number generator (RNG) to generate true random number.
Please see code attached.
When i run it, it get stuck in  "while(RNG_GetFlagStatus(RNG_FLAG_DRDY)== RESET)" loop, ie number isnt ready to be read.
Am I missing the setup of some register.
