Link all my code beginning from address 0

[Altera_Forum]

Hello, 

 may be, this is a simple question, but I can't find the answer as quickly as I wish. ;-) I just want to link all my code and the code of some (used) HAL functions starting from address 0. This question arises from the fact, that I have build custom memory controller that maps accesses on the avalon bus in the lower 1MB range to some external SRAM. There I want to place all my code. To download the code, I planned to use the GERMS Monitor for the NIOS II (found here in the forum). So all I now have to know is, how can I instruct the Linker to continously link the code starting from address 0? In the NIOS 2 IDE, it is only possible to specify some installed memories, where the linker section .text, .rodata, etc. shall be placed. In those pull-down-menus my memory controller doesn't appear. Can I change this?  Thanks for any replies.  Regards.

Hi GrubenKarlo,

The quickest (for experimenting) is to use objcopy to change the section addresses. E.g.:  nios2-elf-objcopy --change-section-address .text=0 foo.elf  You might need to move your other sections as well (.data, .bss, .sbss).  In the long run, you will probably want to just pass the -Ttext option to ld.  Regards, --Scott
