Problem about porting u-boot 1.1.4 to MPC8560

[enorm]

Hi,
    After prog u-boot image to 8560. We get output as follows:

then it can't go on running. we checked ,found it falled in "relocate_code"
,then we write a progam to test memory, we found test failed(say write some
thing to 0-0x8000000 then read)



How can we do to fix this problem?
