This plugin adds support for the AVR architecture to binaryninja. All instructions should be implemented, lifting is mostly implemented.
Run this command in your BN plugins folder:
git clone https://github.com/fluxchief/binaryninja_avr.git
Another option is to download this repository as a ZIP file and extract it in your BN plugins folder.
How is it different than binja_avr?
- This project aims for a better support of different chips. It currently has
- ATMega16
- ATMega168 / ATMega328
- ATTiny48
- ATTiny88
- ATXMega128A4u
support and can be easily extended.
-
This plugin also lifts the AVR instructions. While I at first intended to add lifting to
binja-avr, the changes would have been to large so that I decided to write this plugin from scratch instead. -
Interrupt vectors are defined automatically. (currently disabled, see issue #5).
-
Xrefs on memory.
"Awesome"! Please create a ticket and don't forget to upload your sample there as well (if possible).
- RAMPX/RAMPY/RAMPZ not used - This isn't lifted as much as it could be and decreases the readability of the code, so I disabled the use of these registers.
- Skip instruction followed by a 4 bytes instruction potentially breaks. This is a limitation of BN. BN only sends the raw bytes until the end of the basic block to the plugin, so there is no way we can figure out whether the length of the next instruction is 2 or 4 bytes. It seems to be 2 bytes most of the cases, so I hardcoded it to 2.
- Flags aren't used properly (in lifting).
