How to use .elf file as input into the project

[arvind.rathod]

Hello All

Scenario:
I have 2 projects. For instance proj1 and proj2.
proj1 generated .elf file and this elf file I am givind as input to proj2.

Can I give .elf file input? If yes, then how?
If not, which similar file I can give as input to the project apart from library files?

Please give valuable feedback.
Thanks in advance
