Hi, there
I am a new comer here, and I have met some problem when I was doing the memory test on the TI EVM board.
I used the mtest in uboot. and It seems different address ranges lead different results.
The following is the log:
XXXXXX#mtest 0x9fff0000 0xa0001000 0 1
Pattern 00000000 Writing... Reading...
Mem error @ 0xA0000004: found 0000400B, expected 00004001
Tested 1 iteration(s) with 1 errors.

I mean, if you use the 0x9fff0000 as your start addr. then you get a memory error in the 0xa0000004. But if you change the starting address to 0x9ffc0000, then the memory test pass. No error report. So I guess this is a little werid, and I have read the source code of the mtest function, it is very simple and nothing wrong found there. So I am trapped here and come for help.
Is there anybody else meeting the similar problem? Or some one who can give me some hint?....
Thank you in advance!
