Re: [U-Boot] U-boot PPC405EX with DDR2 DIMM

2013-09-23 Thread Steve Miller
Just wanted to tell the group that I am abandoning using the SPD data on PPC405EX. As I stated earlier, I inherited this design from others. As I dug deeper into the HW, I found that a X64 module was used on a processor that only has a X32 wide bus. Apparently, they could get modules for less tha

[U-Boot] U-boot PPC405EX with DDR2 DIMM

2013-09-18 Thread Steve Miller
Hello, I have inherited a design using the PPC405EX that was based on the Kilauea reference design. One of the changes was Kilauea uses on-board DDR2 DRAM ICs and this design uses DDR2 DIMMs. The u-boot is working, except only 256MB of RAM is available instead of the 1GIG that the module suppo
