Hi,
First of all sorry for intruding in this list. I did not receive any
response in
the user's mailing list. Therefore, I am writing in this forum as my
last resort.
I am trying to simulate the moeg decoder from mediabench 2 on ARM.
The
compilation went fine. The decoder decodes two frames. Then, I get a
panic
message and the simulation stops.
Logs from simulation -
-------------------------------------------------------------------
panic: Page table fault when accessing virtual address 0xe7937004
@ cycle 35935688000
[invoke:build/ARM_SE/sim/faults.cc, line 65]
Memory Usage: 2141836 KBytes
Program aborted at cycle 35935688000

And here is an execution trace of instruction before the panic -

Any pointers on what could be wrong or how can I go about solving it
?
Thanks,
