Hi,

I've just upgraded the SDRAM on my adm5120 board from 16M to 64M, but while the board is booting, it still reports that only 16M sdram is availible. Since I do not have the source code of the bootloader, is there any way to let the board to boot with 64M sdram, or should I change to another bootloader?

Thanks very much.

Here is the boot message.
