In my personal projects I used QEMU extensively to emulate ARM devices, these are some of my posts on the subject: Hello world for bare metal ARM using QEMU U-boot for ARM on QEMU Busybox for ARM on QEMU Booting Linux with U-Boot on QEMU ARM Linux NFS Root under QEMU ARM emulator Debugging ARM programs inside QEMU QEMU ARM semihosting Emulating […]

ARM926 interrupts in QEMU

April 15, 2012

36

In this post I prepared what I think is the simplest example on how to manage interrupts for the widespread ARM926 core. From this example one can expand the complexity of the interrupt management at will. I’m going to test the functionality with QEMU, emulating the Versatile Platform Baseboard. I based this example on my […]

The videos of the last Free and Open source Software Developers’ European Meeting 2012 have been uploaded. The most interesting videos for me are the following: ARM BoF: state of the ARM architecture porting of various Linux distros (54:40 video) Debian secrets: useful information to get started on using or developing Debian (41:24 video) Multiarch: why […]

Encrypted Linux on USB key

January 3, 2012

20

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 CodeSourcery bare metal toolchain for Cortex-M3

September 3, 2011

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.

Compiling Linux kernel 3.0 with Emdebian ARM toolchain

July 24, 2011

16

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 […]
