First connect the Arduino to the computer using the USB cable. The first step is to extract the program from the microcontroller's flash memory. Use avrdude to read the memory's contents: Extract raw binary: Extract hex: Remember to replace <port> by the actual port that your Arduino is connected to (Google can help you here).

We'll learn the AVR assembly language, look at the different peripherals and the registers that control their behavior, and get very intimate with the ATmega328p datasheet. By the end of the course, you'll have hands-on experience with writing AVR assembly code, as well as understanding and reverse engineering the code generated by the compiler.

A FREE comprehensive reverse engineering tutorial covering x86, x64, 32-bit/64-bit ARM, 8-bit AVR and 32-bit RISC-V architectures.

AVR bootloader – what is it? Part of code that starts BEFORE RESET interrupt. Could be used for self-programmable (i.e. without external device) systems, in case you need to supply firmware update for your IoT device. Bootloader address and behavior configured via FUSEs.

To get the most out of modern reverse engineering and debugging techniques such as fuzzing or concolic execution, sophisticated and correct emulators are required for dynamic analysis. The presented work tries to close this gap by introducing AVRS, a lean AVR emulator prototype developed with the goal of reverse engineering.

2018年3月4日 · Using avr-gcc we have the following indications ( source ): An argument is passed either completely in registers or completely in memory. If the argument size is an odd number of bytes, round up the size to the next even number. Subtract the rounded size from the register number Rn.

AVR: Architecture, Assembly & Reverse Engineering. Back to overview. Explore the hidden depths of the AVR-8 architecture, looking under the hood of the compiler and diving into the MCU's internals!
