Using QEMU to emulate the complete boot procedure of an ARM system using U-Boot, the Linux kernel and Busybox.
Compiling and running Busybox for an emulated ARM platform, using CodeSourcery toolchain and QEMU.
How to compile a vanilla Linux kernel for the Versatile ARM platform, and run it using QEMU.
Instructions to compile and run the U-Boot bootloader inside a QEMU emulation of an ARM platform.
Create a simple "Hello world" program that prints on the serial port of an emulated ARM system, using the CodeSourcery gcc toolchain and the QEMU emulator of the Versatile board.
In this post I suggest a way to have an encrypted Linux installation on a USB key, which to me is useful when I travel and I want to securely access the functionality that desktop Linux offers. I want to have no fear that what I take with me will be stolen, even if what I take with me is a full Linux OS, together with my data and maybe some online passwords saved in the browser.
Using the CodeSourcery arm-none-eabi toolchain to compile a minimal "Hello World" example for Stellaris lm3s6965 microcontroller. The microcontroller is emulated through QEMU and the output is written to a serial port.
The Emdebian project works to bring Debian on embedded platforms, with repositories of custom distributions and toolchains to cross-compile software. I wanted to try their ARM toolchains, and coincidentally the Linux kernel 3.0 has been released in these days, so I tried to cross-compile it and emulate it on QEMU. These tests have been done […]
It came to my attention today that there’s an alternative interpreter for the Python language which is faster and often viable: it’s called PyPy and uses Just-In-Time compilation to execute Python code. Just-In-Time compilation is a technique that is used successfully in many projects: the .NET Framework, Java, QEMU, … and it has also been […]
In embedded software programming there’s often the need to use assembly-level instructions to reach all the functionalities of the processing core. But when the developing is done almost exclusively in C, it is sometimes a burden, often an added complexity and possibly a nuisance to code separate assembly files containing the needed functions. Other than […]
