Thanks for your suggestions, We tried with the CFG_MEMTEST_SCRATCH giving it A1FFFFFC. 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 ?
Regards Praveen

We have successfuuly configured U-boot for our custom board based on PXA255. The Board is having 32 MB ram. I am able to sucessfully run the coimmands, md, mw etc.. But if I give mtest( CFG_ALT_MEMTEST is defined) I am getting dataabort
Hi, on ARM (including PXA), you MUST set CFG_MEMTEST_SCRATCH to a valid RAM address (outside the area to be tested, e.g. the last 32-bit word of your RAM), otherwise the memtest will try to write to address 0 (which is flash).
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"
