I played a little with it and I would say that it is likely that the addresses spaces in use are at 0x10000000 and 0x30c0000. Possibly one of them are the flash and the other the ram. (using 'm68k-elf-objdump -mm68k -D -b binary HTS_100.frg' of course to dissassemble it) The most used subroutines (by grepping for 'jsr'): 199 0x30c45424 172 0x100002cc 82 0x30c71370 81 0x30c557ac 63 0x10000340 61 0x30c4fa10 61 0x30c4f7bc 60 0x30c70efc Perhaps the start of the .frg file can be what should be at address 0x10000000 since at index 340 (the fifth most commonly called jsr) there seems to be a tiny function that moves data from d0 to the stack and then it calls 0x30c4f7bc. It looks like some kind of function dispatcher that could be actual code. I'm not sure this is actually usable for anything, but here it is! ;-) -- Daniel Stenberg -- http://www.rockbox.org/ -- http://daniel.haxx.se/Received on 2005-12-14 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
