# elf2hex

    ./elf2hex [-h] --bit-width BIT_WIDTH --input INPUT.ELF [--output OUTPUT.HEX]

SiFive's Verilog test harnesses can't directly read ELF binaries but are

instead required to be provided with a hexidecimal dump of a particular

width and depth.  This project allows users to easily create these

files.

## Building `elf2hex` from a release

The best way to build `elf2hex` is from the [latest release's

tarball](https://github.com/sifive/elf2hex/releases/download/v1.0.1/elf2hex-1.0.1.tar.gz),

as these releases have been tested.  `elf2hex` uses the standard GNU

build flow:

   tar -xvzpf elf2hex-1.0.1.tar.gz

   cd elf2hex-1.0.1

    ./configure --target=riscv64-unknown-elf

    make

    make install

Building from the tarballs requires Python 3.5 (or newer) as well as a C

compiler, as well as a RISC-V toolchain.

## Building `elf2hex` from git

The latest source for `elf2hex` can be found on [SiFive's

GitHub](https://github.com/sifive/elf2hex).  While the master branch is

always meant to be stable, there are no guarantees.  To build from

git sources you must regenerate the build scripts from their sources and

then follow the standard build flow

    git clone git://github.com/sifive/elf2hex.git

    cd elf2hex

    autoreconf -i

    ./configure --target=riscv64-unknown-elf

    make

    make install
