# Installing the STM32L4 gcc development chain on Ubuntu 
#   (may be incomplete...  tested on Ubuntu 15.10.)
#################################################################################

# Install the needed tools for compiling

    sudo apt-get install gcc g++ git autoconf automake libusb-1.0-0-dev


# Now get the required cross-compiler, library, and debugger for the arm processors
#
# Update 1/20/2019: One student reports gdb-arm-none-eabi is not in current repositories... If
# you get an error with the command below, try:
#     sudo apt-get install gcc-arm-none-eabi libnewlib-arm-none-eabi gdb-multiarch

  sudo apt-get install gcc-arm-none-eabi libnewlib-arm-none-eabi gdb-arm-none-eabi


# As far as I know, the stlink utilities for talking to the development
# boards are not pre-packaged.  You'll have to clone the git repository
# and compile the utilities yourself:

  git clone https://github.com/texane/stlink
  cd stlink
  ./autogen.sh
  ./configure --prefix=/usr/local
  make -j 2
  sudo make install


# udev rules:  Grab the 99-libusb.rules file from the course web site
#    http://www.eece.maine.edu/~hummels/classes/ece486/stm32l476.html
# and (as root) install in /etc/udev/rules.d

  sudo wget -N -P /etc/udev/rules.d/ http://web.eece.maine.edu/~hummels/classes/ece486/src/99-libusb.rules



# Optional:  For a graphical debugger, I've used ddd.  (Let me know if you find 
# a way to get the eclipse ide to work.  It should be possible, but I have not
# given it too much effort.)

  sudo apt-get install ddd


# Now install the libraries needed for ECE 486.  This download includes portions
# of the STM32cubeL4 software distributed by STM.
# ECE 486 routines are also provided to configure the 
# processors for real-time "double-buffering" applications.  
# The STM32L476G-Discovery board is supported.
#
# You'll need to download, compile, and install the libraries.  By default, the
# "make install" step will install the libraries in /usr/local/stmdev/

  wget -N http://web.eece.maine.edu/~hummels/classes/ece486/src/stmdevel.zip
  unzip -d stmdevel stmdevel.zip
  cd stmdevel/build
  make
  sudo make install
