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
