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

Maybe you should contact your Applied Microsystems support or FAE?
Best regards,

Never underestimate the power of human stupidity when it comes to
using technology they don't understand.
