- XES XPedite1000 Board
-
- Last Update: December 29, 2003
-=======================================================================
-
-This file contains some handy info regarding U-Boot and the XES
-XPedite1000 PPC440GX PrPMC board. See the README.ppc440 for additional
-information.
-
-
-SWITCH SETTINGS & JUMPERS
-==========================
-
-Jumpers selected for AMD29LV040B flash part as the boot flash.
-
-
-I2C Strap EEPROM & Environment Settings
-=======================================
-
-The XPedite1000 uses a single I2C eeprom for the 440 strappings and for
-the environment variables. The first page (256 bytes) contains the
-strappings and the 2 EMAC HW Ethernet addresses. Be careful not to
-change the 1st page of the EEPROM! Unpopulated jumper J560 can get you
-out of trouble as it disables the strapping read from EEPROM.
-
-I2C probe
-=====================
-
-The i2c utilities work and have been tested on Rev B. of the 440GX. See
-README.ebony for more information about i2c probing with the 440.
-
-
-GETTING OUT OF I2C TROUBLE
-===========================
-
-(Direct quote from README.ebony)
-If you're like me ... you may have screwed up your bootstrap serial
-eeprom ... or worse, your SPD eeprom when experimenting with the
-i2c commands. If so, here are some ideas on how to get out of
-trouble:
-
-Serial bootstrap eeprom corruption:
------------------------------------
-Power down the board and set the following straps:
-
-J560 - closed
-
-This will select the default sys0 and sys1 settings (the serial
-eeproms are not used). Then power up the board and fix the serial
-eeprom using the 'i2c mm' command. Here are the values I currently
-use:
-
-=> i2c md 50 0 10
-
-0000: 85 7d 42 06 07 80 11 00 00 00 00 00 00 00 00 00 .}B.............
-
-Once you have the eeproms set correctly change the
-J560 straps as you desire.
-
-
-PPC440GX Ethernet EMACs
-=======================
-
-The XES XPedite1000 uses emac 2 & 3 and ignores emac 0 & 1. PHYs are connected
-only to emac 2 & 3. The HW Ethernet addresses are read from the i2c eeprom and
-placed in the bd info structure for enet2addr and enet3addr. The ethernet driver
-senses that enetaddr and enet1addr are 0's and does not use them.
-
-As of this writing gigabit ethernet and the TCPIP acceleration hardware is not
-supported.
-
-
-Flash Support
-=============
-
-As of this writing, there is support for the 1/2mb boot flash only. User flash
-is not yet supported.
