Hi, I hope it is the good mailing list for these questions ; if it's not case, excuse me and say me where is the best place. I use a powerpc-elf-gcc compiler to target a MPC8247. I would like to compile a tiny boot and application that run in Flash area (Read-Only). I think to lock stack in Data cache, and use internals DPRAMs of MPC8247 (4KB x 2) for .sdata, .sdata2, .data, .bss and .sbss sections. Which is the best solution to do that ? I try to use -fPIC -ffixed-r14 to use Global Offset Table, but i don't know how GOT works ;-( Does anyone have a good web link or simple example about GOT with a powerpc ? Thanks, Sebastien.
