How to Frosted on QEMU

# Create dir
mkdir frosted-qemu
cd frosted-qemu

# Clone frosted
git clone git@github.com:insane-adding-machines/frosted.git
cd frosted
git submodule init
git submodule update
cd frosted-userland
git submodule init
git submodule update
cd ../..

# get the latest toolchain
wget https://github.com/insane-adding-machines/crosstool-ng/releases/download/v16.07.003/arm-frosted-eabi-5.3.0_16.07.003.tar.bz2
tar xjf arm-frosted-eabi-5.3.0_16.07.003.tar.bz2
export PATH=`pwd`/arm-frosted-eabi/bin:$PATH

# Ensure that pre-requisites to compile qemu are in place. On a debian system this is:
apt-get build-dep qemu

# Get modified qemu
git clone git@github.com:insane-adding-machines/qemu.git
cd qemu
./configure --prefix=`pwd`/../qemu-bin --target-list=arm-softmmu
make
make install
cd ..
export PATH=`pwd`/qemu-bin/bin:$PATH

# Back to the frosted directory
cd frosted

# Copy the included frosted-kernel.config to kconfig/.config
wget https://git.io/vKgD8 -O kconfig/.config

# Copy the included frosted-userland.config to frosted-userland/kconfig/.config
wget https://git.io/vKgDR -O frosted-userland/kconfig/.config

# Compile frosted
make

# Execute with qemu
make qemu2

# As alternative: start qemu and wait for the debugger...
make qemu


# From another console run arm-none-eabi-gdb and attach to localhost:3333 to start debugging
# You can use the following settings in your local .gdbinit script:
#
 tar ext :3333
 layout src
 file kernel.elf
 stepi
