| | Introduction ELF is the file format used for object files (.o's), binaries, shared libraries and core dumps in Linux. It's actually pretty simple and well thought-out. ELF has the same layout for all architectures, however endianness and word size can differ; relocation types, symbol types and the like may have platform-specific values, and of course the contained code is arch specific. An ELF file provides 2 views on the data it contains: A linking view and an execution view. Those two views can be accessed by two headers: the section header table and the program header table. Linking view: Section Header Table (SHT) The SHT gives an overview on the sections contained in the ELF file. Of particular interest are REL sections (relocations), SYMTAB/DYNSYM (sym...

| Welcome to 'Alice in Wonderland'! For a university research project using an ARM Cortex-M33 we are evaluating position-independent code as way to load applications or part of it with a bootloader. It sounds simple: just add -fPIC to the compiler settings and you are done. Unfortunately, it is not that simple. That option opened up...
