Your SDRAM configuration is wrong or your board layout doesn't support the faster speeds.
Just wanna to confirm one thing. If one board's SDRAM init was good enough but with poor layout (Layout design or PCB Processing), it would crash like this? Could it boot after relocation?
I know my assumption isn't reasonable. Well, I have a similar experience on 823. That board could only get the output before relocation in u-boot. Never for booting Linux. After a fix on some pull-ups around CPU and good PCB processing, it worked fine.
So I can make sure one thing. Not all crash after relocation is due to SDRAM init. That's just our software engineer/developer can do. Perhaps it is related with mini error on schematic design or PCB layout including processing.
A little bit out of topic. Sorry for this:-)
