Subject: PowerTAP on MPC8260

Message-ID: <PCIKAHFJJHIFDFAA@mailcity.com> (raw)
Hi All,
I am using PowerTAP on MPC8260.
I am facing the problem of memory corruption when
a piece of code is run with memory translations enabled.
But that doesn't happen if the memory is not translated.
The following instructions are executed:
stwu r1, 0x20(r1)
mfpsr r0, DSISR
li r0, 0
After the the second instruction is executed, r1 gets
again decremented by 0x20. The contents of (r1)+0x20+0x20 are modified.
Kindly help me. Thanks in advance.
Manisha
