Actually having the .elf file is critical to being able to analyze code and data usage. But having the raw .elf file isn't that helpful. What you really need is a link map or a listing file, but you can easily generate those from the elf file using avr-nm and avr-objdump ELF says that dynamic linking is the process of linking a "shared object" to an "executable file". A "relocatable file" is definitely not the same as a "shared object" (a shared object contains some special sections to tell the os which linker it should use to produce the process image etc.) according to elf. Rice grain porcelain techniqueObject file by default, the object file name for a source file is made by replacing the extension .c, .i, .s etc with .o Table w.1 The following Figure shows the steps involved in the process of building the C program starting from the compilation until the loading of the executable image into the memory for program running. The READ_IMPLIES_EXEC work-around was designed for old toolchains that lacked the ELF PT_GNU_STACK marking under the assumption that toolchains that couldn't specify executable permission flags for the stack may not Actually having the .elf file is critical to being able to analyze code and data usage.

Also, as an aside, it probably would have been better to start a new thread on this one, rather than resurrecting a three-years-old one. I'm a brand new user so I'm not sure of my way around the system yet. I want to change my computer's name, so I tried to edit the name in /etc/hostname, but it is a read-only file.

This file will here be called the "1ST_READ.BIN", although any name is possible as long as it is correctly specified in the IP.BIN. When the 1ST_READ.BIN has been loaded, control is passed to the IP.BIN, which will in turn pass it to the 1ST_READ.BIN. The following sections will explain the structure of these files, and how you can create your own. The output file created by ld is in a format called ELF. Various file formats are available for storing executable code. The ELF format works fine when you have an OS around, but since we are going to run the program on bare metal, we will have to convert it to a simpler file format called the binary format.

hackme: Deconstructing an ELF File A friend recently asked me to find the password for a little hard-to-hack program he had written and I agreed to it. The short journey of a few hours that led me to its password were extremely interesting and this article describes the process as well as some of the new techniques learnt along the way.
It works fine for plain-text files, but when I try to transfer executable files, fread() doesn't seem to read the files, only reading "ELF" into the buffer. My question is, what is the proper way to read the contents of an ELF file into a buffer in C? Thank you.
