- Freescale MPC837xE-RDB Board
- -----------------------------------------
- 1. Board Description
- The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E,
- MPC8378E, and the MPC8379E processors in a Mini-ITX form factor.
- The MPC837xE-RDB's have the following common features:
- A) 256-MBytes on-board DDR2 unbuffered SDRAM
- B) 8-Mbytes NOR Flash
- C) 32-MBytes NAND Flash
- D) 1 Secure Digital High Speed Card (SDHC) Interface
- E) 1 Gigabit Ethernet
- F) 5-port Ethernet switch (Vitesse 7385)
- G) 1 32-bit, 3.3 V, PCI slot
- H) 1 32-bit, 3.3 V, Mini-PCI slot
- I) 4-port USB 2.0 Hub
- J) 1-port OTG USB
- K) 2 serial ports (top main console)
- L) on board Oscillator: 66M
- The MPC837xE-RDB's have the following differences:
- MPC8377E-RDB MPC8378E-RDB MPC8379E-RDB
- SATA controllers 2 0 4
- PCI-Express (mini) 2 2 0
- SGMII Ports 0 2 0
- 2. Memory Map
- 2.1. The memory map should look pretty much like this:
- Address Range Device Size Port Size
- (Bytes) (Bits)
- =========================== ================= ======= =========
- 0x0000_0000 0x0fff_ffff DDR 256M 64
- 0x1000_0000 0x7fff_ffff Empty 1.75G -
- 0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M 32
- 0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M 32
- 0xe030_0000 0xe03f_ffff PCI I/O space 1M 32
- 0xe000_0000 0xe00f_ffff Int Mem Reg Space 1M -
- 0xe060_0000 0xe060_7fff NAND Flash 32K 8
- 0xfe00_0000 0xfe7f_ffff NOR Flash on CS0 8M 16
- 3. Definitions
- 3.1 Explanation of NEW definitions in:
- include/configs/MPC837XERDB.h
- CONFIG_MPC83XX MPC83xx family for both MPC8349 and MPC8360
- CONFIG_MPC837X MPC837x specific
- CONFIG_MPC837XERDB MPC837xE-RDB board specific
- 4. Compilation
- Assuming you're using BASH shell:
- export CROSS_COMPILE=your-cross-compile-prefix
- cd u-boot
- make distclean
- make MPC837XERDB_config
- make
- 5. Downloading and Flashing Images
- 5.0 Download over serial line using Kermit:
- loadb $loadaddr
- [Drop to kermit:
- ^\c
- send <u-boot-bin-image>
- c
- ]
- Or via tftp:
- tftp $loadaddr u-boot.bin
- 5.1 Reflash U-boot Image using U-boot
- tftp $loadaddr u-boot.bin
- protect off fe000000 fe0fffff
- erase fe000000 fe0fffff
- cp.b $loadaddr fe000000 $filesize
- 6. Additional Notes:
- 1) The console is connected to the top RS-232 connector and the
- baudrate for MPC837XE-RDB is 115200bps.
