[U-Boot-Users] mpc5200 relocation problem

Hi, I designed an MPC5200 with 256MB RAM (4 x 512Mb chips; MT48LC32M16A2, 8x16bitx4banks). When I force U-boot to just use the first 128 MB, everything is ok (I force the return value from the routine exploring the RAM size). If I try to use the full 256 MB it crashes in the relocation phase (not always at the same point). I'm quite sure the RAM is working, as a test RAM program, residing in the low RAM and testing the full memory from 0x08000000 to 0x0fffffff, always gives result ok (it's started from U-boot running in low memory). I'm using u-boot 1.1.1

Any suggestion?

Many thanks
