Subject: [openrisc] OR1200 porting MP3 problem
The default sim.cfg use a simmem.cfg to discribe the memory information
00000000 00200000 flash 0 5 5
40000000 00000010 RAM 2 1 1
80000000 00200000 RAM 1 1 2
I don't know this format
Anyone can give a xess.ld file which can link correcttly the mp3 project
or explain how can we modify a xess.ld file when I see a lot of
section need to limit the location
Thank you very much
Regards
Anthony
