When using Oki's flash utility for Oki Advantage Microcontrollers or when creating a ROM image, it is sometimes noted in documents and required to use particular output object formats. Most ARM® compatible compilers, output ELF formatted output files. So how does one get a binary or other output formatted object files?

All ARM compatible software development tools have utilities that handle this task. For example, ARM software development tools (ADS, SDT or RealView) have a utility called fromELF that can convert ELF objects to other formats. GNU tool-chain contains a tool called Object Copy (objcopy.exe) that does the same task and is freely distributed. Similarly, other compilation tools provide comparable utilities for file format conversion.
