It seems that LinuxBIOS copies itself to _RAMBASE, which is 0x4000. Then it branches to 0x4000 into _start, which sets up the stack and calls hardwaremain. The address of hardwaremain from linuxbios_c.o is wrong. The address is not the Flash address and it's not the RAM address. Can someone explain how linuxbios_c.o is linked with RAM addresses?
What do you mean ? In the S2885 I built, the _RAMBASE is 0x4000 and hardwaremain is 0x5fe0 as you can get from the linuxbios_c.map. They are both in RAM. If you use "objdump -drS linuxbios_c.o" you will find the hardwaremain is at offset 0x1fe0 from the _RAMBASSE.
BTW, if you specify the -g option for gcc, you can use the -S option in objdump to see the source code with the disassebmly (-d).
