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).
