Bill,

Great job with the coding! U-boot came up on the first build(with your patches), with no mods <BUBINGA405EP>.

Just a quick note... The memory config on the 405EP Eval board is still incorrect. The Physical DIMM is 64-bit, but the memory bus is 32-bit... therefore, only half of the memory gets used...

In spd_sdram.c, I added a line after 354 that divided 'total_size' by two. This appears to do the init correctly.

BTW-Is anyone able to get a uImage built kernel to boot off a 405EP Eval board? I'd love to know what version... My kernel dies pretty early...

Regards,
