STM32 Developement environment setup
===

Here we provide a brief tutorial of setting up the environment (i.e., GCC toolchain, debugger, flash tool)

### 0.Prerequisite

sudo apt install build-essential git zlib1g-dev libsdl1.2-dev automake* autoconf* libtool libpixman-1-dev lib32gcc1 lib32ncurses5 libc6:i386 libncurses5:i386 libstdc++6:i386 libusb-1.0.0-dev

### 1.OpenOCD

git clone git://git.code.sf.net/p/openocd/code openocd
cd openocd
./bootstrap
./configure --prefix=/usr/local  --enable-jlink --enable-amtjtagaccel --enable-buspirate  --enable-stlink   --disable-libftdi
echo -e "all:\ninstall:" > doc/Makefile
make -j4
sudo make install

### 2. ST-LINK
:::success

git clone http://github.com/texane/stlink.git
cd stlink
mkdir build
cd build
cmake ..
make -j4
sudo make install
#sudo cp 49-stlinkv2.rules /etc/udev/rules.d/

### 3. ARM GCC toolchain 9

wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/9-2019q4/gcc-arm-none-eabi-9-2019-q4-major-x86_64-linux.tar.bz2
tar jxf ./gcc-arm-none-eabi-9-2019-q4-major-x86_64-linux.tar.bz2
rm gcc-arm-none-eabi-9-2019-q4-major-x86_64-linux.tar.bz2

edit "~/.bashrc" and append the following instruction:

PATH=$PATH:~/workspace/tools/gcc-arm-none-eabi-9-2019-q4-major/bin
