rwcompression

GCC .data/.bss runtime loader and post-build data compressor

• This tool provides the ability to compress/load rw image with gcc binaries, just like what commercial toolchain did (Keil MDK, IAR EWARM, etc)
• Loader: startup_load.c, The only thing need to do is:
  1. add startup_load.c to project
  2. call _mainCRTStartup before main
• Post-build: process.py
  • Everything should be done automatically, even without changing a single line in your link script

---

solve python dependency by:

pip3 install -r requirements.txt

call process.py with a given elf file will generate a patched file patched.elf

python3 process.py firmware.elf

you can use objcopy to generate executable binary from patched.elf directly

objcopy -O binary -S patched.elf patched.bin

patched.elf also can be load & programmed by debuggers automatically
