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. + + +Regards, +--Travis +<travis.sawyer@sandburst.com> |
