linker script vs grub

[aflag]

Grub say that the format is invalid (error 13) if I do something like this on the linker script:

Code: Select all

 
. = 0x1000000;
.start : {
    *(.start) 
}
. = 0xc0000000;

but if I do this

Code: Select all

. = 0x1000000;
.start : {
    *(.start)
} 
. += 0xc0000000;

grub doesn't complain at all. Why does that happen? I intend to place my kernel at 16MB physical address and it should start at 0xc0000000 on virtual address.

Would you mind showing us the rest of the script? Also, what format would we be talking about?
