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> |
