“Using debuginfod with The Yocto Project” by Dorinda Bassey

Debugging information is about 5 to 15 times larger than an Image, and sometimes due to memory or disk space constraints, it is not possible to use GDB directly on the remote target to debug applications because GDB needs to load the debugging information. Hence the need for debuginfod from “elfutils“ which is a way to make debugging information available on a server for easy debug and distribution of “debuginfo“ files.
