But again the same problem..., Data Abort.... My Ram is 32 MB...& so the RAM is from A0000000 to A2000000 Is there anything wrong in the RAM Configuration.?. But I am able to properly write to different location using mw & display it by using md My U-boot is from A07E0000 -> A07F59D8.. What might be the problem ?

To quote the README: "- CFG_MEMTEST_SCRATCH: Scratch address used by the alternate memory test You only need to set this if address zero isn't writeable" Cheers Anders ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
