Freescale MPC837xEMDS 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:

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 MPC837XEMDS 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.
