[U-Boot-Users] [PATCH 2/2] Add support for the MPC837xERDB
Kim Phillips
kim.phillips at freescale.com
Wed Jan 16 07:38:05 CET 2008
MPC837xERDB board support includes:
* DDR2 330MHz hardcoded (soldered on the board)
* Local Bus NOR Flash
* I2C, UART and RTC
* eTSEC RGMII (TSEC0 - RTL8211B with MII;
* TSEC1 - VSC7385 local bus, hardcoded, requires seperate firmware
* load)

+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:
+
+ Address Range Device Size Port Size
+ (Bytes) (Bits)
+ =========================== ================= ======= =========
+ 0x0000_0000 0x0fff_ffff DDR 256M 64
+ 0x1000_0000 0x7fff_ffff Empty 1.75G -
+ 0x8000_0000 0x9fff_ffff PCI1 memory space 512M 32
+ 0xa000_0000 0xbfff_ffff PCI2 memory space 512M 32
+ 0xc200_0000 0xc2ff_ffff PCI1 I/O space 16M 32
+ 0xc300_0000 0xc3ff_ffff PCI2 I/O space 16M 32
+ 0xe000_0000 0xe00f_ffff Int Mem Reg Space 1M -
+ 0xe280_0000 0xe47f_ffff NAND Flash 32M 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 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.
