amd-lm32-smu-dumper

Quick & Dirty tool to dump LM32-based AMD SMU bootrom on patched SMU FW

Dependency

libpci-dev

Build

smurw - the PCI address space bridging tool, needs to be built:

gcc smurw.c -o smurw -lpci

Run

sudo python3 dump_rom.py

Dumping should finish in a few minutes, result is written to rom_dump_0x0.bin.
SMU FW will be interrupted and stop working until next boot, so it's advised to reboot the platform as soon as possible.

Tested on

A4-6210
