Hi All,
I seem to have a Bamboo board that U-Boot hates. Using any version
newer than 1.1.4, I get the following error on boot up:
U-Boot 1.2.0-gb23b5475-dirty (Aug 9 2007 - 09:49:20)
CPU: AMCC PowerPC 440EP Rev. B at 400 MHz (PLB=100, OPB=50, EBC=25 MHz)
I2C boot EEPROM disabled
Bootstrap Option D - Boot ROM Location EBC (16 bits)
Internal PCI arbiter disabled, PCI async ext clock used
32 kB I-Cache 32 kB D-Cache
Board: Bamboo - AMCC PPC440EP Evaluation Board
I2C: ready
DRAM: ERROR: DIMM 0, unsupported refresh rate/type.
Replace the DIMM module with a supported DIMM.
ERROR: Tcyc incorrect for DIMM in slot 0
### ERROR ### Please RESET the board ###
This is a stock board from AMCC from a couple years ago. I haven't
done anything with the DIMMs in it, so they are whatever came with the
board. Both PIBS and U-Boot 1.1.4 report a DRAM size of 192 MB, so
I'm assuming something with the SDRAM probing in newer versions of
U-Boot is causing the error above.
Any ideas?
