Selfection (an RTS tool for TizenRT)

Selfection is an RTS tool for projects written in C that compiles to Arm binary. Selfection uses the arm-none-eabi-objdump and arm-none-eabi-readelf tools to statically build a dependency graph of functions from binaries and detect modified code elements.

Requirements

arm-none-eabi-objdump and arm-none-eabi-readelf should be in PATH environment variable. You can download GNU Arm Embedded Toolchain from here.

Usage

python -m selfection.callgraph rts -h

usage: TOOL rts [-h] [--dir DIR] [--skip SKIP] [--debug] [--syms] BINARY

positional arguments:
  BINARY       binary file

optional arguments:
  -h, --help   show this help message and exit
  --dir DIR    cache directory for dependencies
  --skip SKIP  file path of skipped functions
  --debug      Enable debug output
  --syms       Enable tracking of symbols
