NIOS II IDE How to add a post process for the .elf file

Hi all,

I am using ther NIOS II IDE (19.1) on linux.

After building the project.elf I want to create also other files from the elf. How I can add the additional steps in build process or add a new build target wich is accepted from the build system.

It will also be helpfull if I have some documentation about this aspect of the NIOS II IDE.

Thank you in advance.
