I'm not sure what reset vector is. I am assuming that you are talking about CFG_RESET_ADDRESS, which I have set to 0x80000000. I'm not sure exactly what to set that to, since some board configuration files
See in do_reset() [in cpu/*/cpu.c] how CFG_RESET_ADDRESS gets used.
To my knowledge,reset vector is decided by Hardware Circuit of Power-on.In PowerPC,only two reset vectors are possible.One is 0x00000100,another 0xFFF00100.So
This is correct for the many, but not for all PowerPC processors. The IBM 4xx, for example, starts at 0xFFFFFFFC instead.
OK.It's not necessary to set CFG_RESET_ADDRESS.At
It may be necessary if you want that the "reset" command in U-Boot is working as expected.
