# 利用qemu模擬rtos

step1:下載libary

sudo apt-get update
sudo apt-get install build-essential git-core
sudo apt-get install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf
sudo apt-get install qemu-user qemu-system-arm
sudo apt-get install build-essential git zlib1g-dev libsdl1.2-dev libglib2.0-dev "automake*" "autoconf*" libtool libpixman-1-dev
sudo apt-get install lib32gcc1 lib32ncurses5
sudo apt-get install gcc-arm-none-eabi libnewlib-arm-none-eabi

step2:下載rtos程式碼做測試

mkdir -p workspace
cd workspace
git clone git://github.com/beckus/stm32_p103_demos.git || git clone https://github.com/beckus/stm32_p103_demos.git 
git clone git://github.com/beckus/qemu_stm32.git || git clone https://github.com/beckus/qemu_stm32.git

cd qemu_stm32
git submodule update --init dtc || sudo apt-get install libfdt-dev
./configure --disable-werror --enable-debug \
        --target-list="arm-softmmu" \
        --extra-cflags=-DSTM32_UART_NO_BAUD_DELAY \
        --extra-cflags=-DSTM32_UART_ENABLE_OVERRUN \
        --disable-gtk
make
cd ../stm32_p103_demos
make all
make blink_flash_QEMURUN
make button_QEMURUN
make uart_echo_QEMURUN

step3:測試rtos

cd ~/workspace
git clone [e-mail]:embedded2015/freertos-basic.git
cd freertos-basic
make
make qemu 

* make qemu是主要執行程式碼
