Hello,
I have been using the Riscwatch box w/ RISCwatch ver. 5.1 software. I am running Linux on our embedded PPC405D. The trace captures the instructions with their virtual addresses. However, when an interrupt is detected, the processor uses the physical addresses, at which point Riscwatch complains it is "not configured" to read those addresses. I suspect that it thinks that the physical address is virtual, so when it goes into the TLB and/or page table for the translation, it can't find it since there isn't obviously a translation. In other words, I think that Riscwatch should switch to real mode instead at that point. How can configure RISCwatch to access those interrupt address locations that need physical address? Anyone encountered this problem and found a way around it? I e-mailed IBM about it, but haven't gotten a response yet...
Thanks,
NN
