Hello ,
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
as below..

$ mtest 0xa1000000 0xa1ffffff 1
Testing a1000000 ... a1ffffff:
data abort      1
pc : [<a07e52ac>]    lr : [<a07f00f8>]
sp : a07bddb4  ip : a07bdc48  fp : a07bddf8
r10: a1ffffff  r9 : 00000000  r8 : a07bdfdc
r7 : 00000000  r6 : a1000000  r5 : fffffffe  r4 : 00000001
r3 : a07f2d1c  r2 : a07f2d63  r1 : a07bdc7c  r0 : 0000000d
Flags: nzCv  IRQs off  FIQs off  Mode <NULL>

What could be wrong ?
Also if I undefine CFG_ALT_MEMTEST, & do mtest I am not getting any
exception & am able to test..
Why is that I am not able to test if CFG_ALT_MEMTEST is enabled..?
TIA
Regards
Praveen
