  1. Freescale MPC837xE-RDB Board
  2. -----------------------------------------
  3. 1. Board Description
  4. The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E,
  5. MPC8378E, and the MPC8379E processors in a Mini-ITX form factor.
  6. The MPC837xE-RDB's have the following common features:
  7. A) 256-MBytes on-board DDR2 unbuffered SDRAM
  8. B) 8-Mbytes NOR Flash
  9. C) 32-MBytes NAND Flash
  10. D) 1 Secure Digital High Speed Card (SDHC) Interface
  11. E) 1 Gigabit Ethernet
  12. F) 5-port Ethernet switch (Vitesse 7385)
  13. G) 1 32-bit, 3.3 V, PCI slot
  14. H) 1 32-bit, 3.3 V, Mini-PCI slot
  15. I) 4-port USB 2.0 Hub
  16. J) 1-port OTG USB
  17. K) 2 serial ports (top main console)
  18. L) on board Oscillator: 66M
  19. The MPC837xE-RDB's have the following differences:
  20. MPC8377E-RDB MPC8378E-RDB MPC8379E-RDB
  21. SATA controllers 2 0 4
  22. PCI-Express (mini) 2 2 0
  23. SGMII Ports 0 2 0
  24. 2. Memory Map
  25. 2.1. The memory map should look pretty much like this:
