Memory Map changes
Address 0x80001800 is an unused exception area. Its not a stub loader or anything standard. Its documented in most PPC manuals.
where are the memory protection registers?
Nuke, I based my edit on this IRC discussion with bushing. Do you know better than him? Or did you have some other reason for reverting my edit?
| 14:22:44 | jepler | "The top of MEM2 memory is allocated to Starlet. You can access this memory by disabling memory protection via hardware registers. (See Memory Interface. TODO). " -- wiki. hmm, is it the wii version of what is called 'MI' http://hitmen.c02.at/files/yagcd/yagcd/chap5.html#sec5.5 ? or is it something different than this? |
| 14:27:00 | bushing | jepler: completely different |
| 14:27:08 | jepler | bushing: OK, thanks for saving me the time of barking up that tree |
| 14:27:33 | bushing | MI is a way to get an interrupt (internally generated by the PPC) when you access a specific area of memory |
| 14:27:59 | bushing | the Starlet memory protection is a few registers that can only be set by running code on the starlet |
| 14:28:05 | bushing | (I've done it) |
