  • In addition to the ARM’s MMU, BCM2835 includes a second coarse-grained MMU for mapping ARM physical addresses onto system bus addresses.
  • There is one C library for BCM2835 which is compatible with BCM2708. Only with the GPIO pins different.
  • The GPIO pin numbering as used by RPi is different to and inconsistent with the underlying BCM 2835 chip pin numbering. http://elinux.org/RPi_BCM2835_GPIOs.
