  1. Sincerely, I don't have any idea on how it could work on windows. I've ordered my tiny computer already, but couldn't wait for it to mess up with configurations and kernel tweaking!
  2. A Raspberry Pi emulated environment on OSX Lion To set up an emulated environment of the Raspberry Pi software on OSX one will need:A Cross-Compiling Tool for the CPU architecture of RPi. ( eg. ARM EABI Toolchain ) The RPi Kernel. The RPi root filesystem. The Emulator (QEMU). The Cross-Compiling Tool for the ARM architecture. Assuming one already have the latest Xcode and command line tools from Apple Developer and homebrew installed, then should install the dependencies: brew install mpfr gmp libmpc libelf texinfo Grab and compile the tool: mkdir ~/rpi mkdir ~/rpi/arm-cs-tools git clone https://github.com/jsnyder/arm-eabi-toolchain.git cd arm-eabi-toolchain PREFIX=$HOME/rpi/arm-cs-tools make install-cross make clean echo “export PATH=$HOME/rpi/arm-cs-tools/bin:$PATH†» ~/.bash_profile The RPi Kernel Compilation mkdir ~/rpi/kernel cd ~/rpi/kernel git clone https://github.com/raspberrypi/linux.git cd linux Grab the config file and configure the kernel: cp arch/arm/configs/bcmrpi_cutdown_defconfig .config make ARCH=arm CROSS_COMPILE=~/rpi/arm-cs-tools/bin/arm-none-eabi- menuconfig Save the configuration and let’s build the kernel afterwards. Note that the compilation should fail and complain about an <elf.h> inclusion in scripts/mod/mk_elfconfig. If it does, one must create the file: sudo touch /usr/local/include/elf.h Edit it and write the following: #include <libelf.h> #define R_386_NONE 0 #define R_386_32 1 #define R_386_PC32 2 #define R_ARM_NONE 0 #define R_ARM_PC24 1 #define R_ARM_ABS32 2 #define R_MIPS_NONE 0 #define R_MIPS_16 1 #define R_MIPS_32 2 #define R_MIPS_REL32 3 #define R_MIPS_26 4 #define R_MIPS_HI16 5 #define R_MIPS_LO16 6 and follow through the building process: make ARCH=arm CROSS_COMPILE=~/rpi/arm-cs-tools/bin/arm-none-eabi- -k The image file is created and located as arch/arm/boot/zImage. The Emulator Due to a bug of a white screen hanging QEMU if compiled with llvm one must install the package apple-gcc42 from the homebrew’s dupes repository. brew install homebrew/dupes/apple-gcc42 And then compile and install qemu like: brew install qemu —use-gcc Now we’re left with all we need to start the RPi distribution so let’s start it like: qemu-system-arm -M versatilepb -cpu arm1176 -hda debian6-19-04-2012.img -kernel zImage -append “root=/dev/sda2†-serial stdio -usbdevice tablet and...
