- AMCC Ebony Board
-
- Last Update: September 12, 2002
-=======================================================================
-
-This file contains some handy info regarding U-Boot and the AMCC
-Ebony evaluation board. See the README.ppc440 for additional
-information.
-
-
-SWITCH SETTINGS & JUMPERS
-==========================
-
-Here's what I've been using successfully. If you feel inclined to
-change things ... please read the docs!
-
-DIPSW U46 U80
-------------------------
-SW 1 off on
-SW 2 on on
-SW 3 on on
-SW 4 off on
-SW 5 on off
-SW 6 on on
-SW 7 on off
-SW 8 on off
-
-J41: strapped
-J42: open
-
-All others are factory default.
-
-
-I2C probe
-=====================
-
-The i2c utilities have been tested on both Rev B. and Rev C. and
-look good. The CONFIG_SYS_I2C_NOPROBES macro is defined to prevent
-probing the CDCV850 clock controller at address 0x69 (since reading
-it causes the i2c implementation to misbehave. The output of
-'i2c probe' should look like this (assuming you are only using a single
-SO-DIMM:
-
-=> i2c probe
-Valid chip addresses: 50 53 54
-Excluded chip addresses: 69
-
-
-GETTING OUT OF I2C TROUBLE
-===========================
-
-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:
-
-J41 - open
-J42 - strapped
-
-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: bf a2 04 01 ae 94 11 00 00 00 00 00 00 00 00 00 ................
-
-=> i2c md 54 0 10
-0000: 8f b3 24 01 4d 14 11 00 00 00 00 00 00 00 00 00 ..$.M...........
-
-Once you have the eeproms set correctly change the
-J41/J42 straps as you desire.
-
-SPD eeprom corruption:
-------------------------
-I've corrupted the SPD eeprom several times ... perhaps too much coffee
-and not enough presence of mind ;-). By default, the ebony code uses
-the SPD to initialize the DDR SDRAM control registers. So if the SPD
-eeprom is corrupted, U-Boot will never get into ram. Here's how I got
-out of this situation:
-
-0. First, _before_ playing with the i2c utilities, do an 'i2c probe', then
-use 'i2c md' to capture the various device contents to a file. Some day
-you may be glad you did this ... trust me :-). Otherwise try the
-following:
-
-1. In the include/configs/EBONY.h file find the line that defines
-the CONFIG_SPD_EEPROM macro and undefine it. E.g:
-
-#undef CONFIG_SPD_EEPROM
-
-This will make the code use default SDRAM control register
-settings without using the SPD eeprom.
-
-2. Rebuild U-Boot
-
-3. Load the new U-Boot image and reboot ebony.
-
-4. Repair the SPD eeprom using the 'i2c mm' command. Here's the eeprom
-contents that work with the default SO-DIMM that comes with the
-ebony board (micron 8VDDT164AG-265A1). Note: these are probably
-_not_ the factory settings ... but they work.
-
-=> i2c md 53 0 10 80

-PCI DOUBLE-ENUMERATION WOES
-===========================
-
-If you're not using PCI-X cards and are simply using 32-bit and/or
-33 MHz cards via extenders and the like, you may notice that the
-initial pci scan reports various devices twice ... and configuration
-does not succeed (one or more devices are enumerated twice). To correct
-this we replaced the 2K ohm resistor on the IDSEL line(s) with a
-22 ohm resistor and the problem went away. This change hasn't broken
-anything yet -- use at your own risk.
-
-We never tested anything other than 33 MHz/32-bit cards. If you have
-the chance to do this, please let me know how things turn out :-)
-
-
-Regards,
---Scott
