| | | | | In my last post, we managed to dump the firmware off of an Xbox One controller by using the Single Wire Debug interface. Now that we have the firmware image as well as the target CPU determined, we can load it into Ghidra and attempt to learn more about how it works. For this post, we are focusing on learning more about how the firmware image works by writing a proper Ghidra loader and reviewing the USB stack. | |

| | | | | It seems that the bootstrap code is just scattered around various memory addresses and there's no simple way to dump all of it, so i decided to just dump a chunk of memory from 0x00000000 and look for any reference to addresses outside of that chunk (allowing me to build up a basic map of the code). Although the exact addresses vary between disk models, my layout should give you a good idea where to look. | |

| | | | | You may have seen the Analog.coop site recently and found some of the easter eggs, like the grid hot keys. I loved the concept, and made a mental note to spend some time reverse engineering/rebuilding it for my own uses. Well it just so happens that the guys at Analog have released the #grid on Github, which is great because it made it easier for me to adapt the code and do some small improvements. | |
