Previously, we discussed how to run the RISC-V kernel on QEMU. Now, let’s talk about how to use Eclipse + GDB to debug the kernel on the QEMU platform. ${SIFIVE_DIR} is the local root directory of the freedom-u-sdk open-source project. 1. Configure BBL Configure the bootloader and generate debugging information. Enter the ${SIFIVE_DIR}/work/riscv-pk directory, which … Read more
This tutorial includes some sample programs that can be debugged hands-on to deepen understanding. To debug ARM programs, we need an environment that can run ARM programs and a debugger that supports the ARM architecture. This tutorial will introduce how to set up an ARM cross-compilation, running, and debugging environment based on the x86 platform … Read more
Firmadyne is an open-source software for automated analysis of embedded Linux system security, developed by Carnegie Mellon UniversityDaming D. Chen. It supports batch detection, with the entire system including firmware crawling, root filesystem extraction, QEMU simulation execution, and vulnerability discovery. The system can be downloaded from github: https://github.com/firmadyne/firmadyne The framework is shown in the figure … Read more
Abstract:In recent years, the application of Bluetooth devices has become increasingly widespread. If there are vulnerabilities in Bluetooth devices, it may lead to information leakage, economic losses, and other consequences. However, the firmware updates for Bluetooth devices are often delayed, and some cannot even perform hot updates. Currently, there is a relative lack of tools … Read more

Introduction Remote debugging with QEMU is quite simple; just enable the -g parameter to bind to a local port. However, IDA requires some configuration to debug MIPS architecture binary files and pause processes for debugging. (There are many online tutorials on how to run IDA in Linux and set up the buildroot environment, or feel … Read more
Debugging C programs used to confuse me. However, when I was writing my operating system, I had many bugs to debug. I was fortunate to use the QEMU emulator, which allowed me to attach a debugger to my operating system. This debugger is gdb. — Julia Evans This article navigation ◈ 1.

Because I need some knowledge related to embedded Linux in my work, I started to learn. Yocto is a complete set of tools under the Linux Foundation used to build Linux for embedded devices. With Yocto, we can create our own Linux system for our embedded devices, customize and trim the necessary modules, and package … Read more
Today, I will teach you how to run a RISC-V Linux on the QEMU emulator. A RISC-V Linux includes: opensbi linux root filesystem 1. Download RISC-V Toolchain Downloading the toolchain source code and compiling it can lead to incorrect options, so we will use the precompiled toolchain instead.
