ELF is an extremely flexible format for representing binary code in a system

ELF is an extremely flexible format for representing binary code in a system. By following the ELF standard you can represent a kernel binary just as easily as a normal executable or a system library. The same tools can be used to inspect and operate on all ELF files and developers who understand the ELF file format can translate their skills to most modern UNIX systems.

Antenna preamplifier design for ELF Schumann resonances receiver

I'm interested in listening to extremely low frequency band below 100Hz, where the famous Schumann resonances reside. I will use a large T shape antenna together with a very low noise, very high impedance preamplifier. This is my current draft of…

Do transformers generate ELF waves?

Do AC transformers (particularly the 60 hertz ones) generate an Extremely Low Frequency (ELF) wave at 60 hertz or is it just a plain oscillating magnetic field with no electronic part 90º out of phase like normal RF waves.

Linking and the ELF - use of PC-relative addressing, GOT and PLT

So that we're on the same page, I'll try to explain what I think I know about Symbol Relocation and ask questions as they come up. Symbol Relocation: Absolute addresses – replace the reference for the actual address. This happens when a global…

Simple relocatable image format options

I am writing firmware for an ARM platform in which I want to have the main bootloader relocatable in memory rather than always loaded at a fixed address during boot. This means that I need a relocatable format stored in Flash, like ELF. If ELF is…
