After developing an embedded system, we always need to be able to identify and fix some bugs that could not be seen during development process. This requirement implies that the development team must include in the target system some tools and procedure to detect and report those bugs.
During this presentation, we will see several techniques that can apply for this need. Using the coredump feature of the Linux kernel, we will generate coredumps and use gdb to inspect them. Then we will check some of the internals of a Linux elf coredump and use binutils to handle it. Finally, we will talk about cortex, a software that do on-the-fly conversion of a coredump to a much smaller text file.
