One Introduction Often, programs run without an operating system, which is known as bare-metal operation and cannot run directly in Linux. Therefore, alternative methods must be used for analysis. Taking a CTF problem as an example, we will learn about analyzing bare-metal programs on the ARM architecture. Two Analysis Program address: https://dn.jarvisoj.com/challengefiles/confusedARM.hex.f4e616545ff1a18526b9d1c90ea648ff This program is … Read more
Click the blue "Arm Selected" in the upper left corner and select "Set as Star" Note: This article primarily discusses the ARMV8-aarch64 architecture, gicv3, and Linux kernel 5.14 by default. Consideration: Have you ever thought about a scenario where a high-priority interrupt preempts another interrupt that is currently being processed? This is known as interrupt … Read more
ARM defines two low-power interfaces for low power control handshakes, namely Q-Channel and P-Channel. The Q-Channel was discussed previously in “SoC Design Power Consumption – Q Channel“. The Q-Channel is relatively simpler than the P-Channel, as it only controls two states: on and off. This is fine for handshakes controlling clocks, but insufficient for handshakes … Read more

One ARM Assembly Generally, our computers are X86 architecture machines. Here we use clang to compile our files. Compiling files by ourselves and using IDA to learn alongside makes it easier to understand. Two Some instructions about clang: Using clang to directly compile into an executable file // Compile our file into ARMv5 architecture file … Read more
