U-boot loading fails on LS2088

[vijaykumardesai]

When I powerup the LS2088 board, I get an error from the U-boot as described below.

I use the default u-boot available in the board.

Can someone help me understand what the issue is?

I tried to remove the RAM from slot, cleaned it up and tried again. It worked. Dont know what the issue is but it works again now.
