Installing

CMake

Follow this link to download the bash file for Linux and install the latest version of CMake. Example of bash file for Ubuntu cmake-3.12.2-Linux-x86_64.sh. To install cmake from .sh file downloaded run the commands similar to the following:

wget https://cmake.org/files/v$version/cmake-$version.$build-Linux-x86_64.sh
sudo mkdir /opt/cmake
sudo sh cmake-$version.$build-Linux-x86_64.sh --prefix=/opt/cmake

Answer Y for license and answer N for including subdirectory. Then, add your binary link for Cmake.

sudo ln -s /opt/cmake/bin/cmake /usr/local/bin/cmake

Test your Cmake by typing in cmake --version

GNU-MCU-ECLIPSE

A detailed instructions and troubleshooting can be followed in this link to install GNU MCU Eclipse ARM Embedded GCC. The official webpage of gnu instructs installing the compiler in the /opt folder but is not necessary. In the CMakeList.txt, the path to the compiler is pointed to the folder of this repository. A quick installation instruction can be followed below:

1. The GNU/Linux versions of GNU MCU Eclipse ARM Embedded GCC are packed as .tgz archives. Download the latest version from this link named like gnu-mcu-eclipse-arm-none-eabi-gcc-7.3.1-1.1-20180724-0637-centos64.tgz.

2. To install the toolchain, unpack the archive and copy it to/${HOME}/path-to-this-repo/gnu-mcu-eclipse/arm-none-eabi-gcc/ :

3. $ cd <this repo>

4. $ mkdir gnu-mcu-eclipse and $ cd gnu-mcu-eclipse

5. $ mkdir arm-none-eabi-gcc and cd arm-none-eabi-gcc

6. $ tar xf ~/Downloads/gnu-mcu-eclipse-arm-none-eabi-gcc-7.3.1-1.1-20180724-0637-centos64.tgz

7. $ chmod -R -w "${HOME}"/path-to-this-repo/gnu-mcu-eclipse/arm-none-eabi-gcc/7.3.1-1.1-20180724-0637

OpenOCD

Follow the instructions in this link to install OpenOCD. Example instructions:

1. Download the latest version from this link named like gnu-mcu-eclipse-openocd-0.10.0-8-20180512-1921-centos64.tgz
2. To install the toolchain, unpack the archive and copy it to/${HOME}/path-to-this-repo/gnu-mcu-eclipse/openocd/ :
3. $ cd <this repo>/gnu-mcu-eclipse
4. $ mkdir openocd and cd openocd
5. $ tar xf ~/Downloads/gnu-mcu-eclipse-openocd-0.10.0-8-20180512-1921-centos64.tgz
6. $ chmod -R -w "${HOME}"/path-to-this-repo/gnu-mcu-eclipse/openocd/0.10.0-8-20180512-1921

STM32F4 Hardware Abstraction Layer

1. Mount the network drive Sandbox (\\fsvs01) to your Ubuntu partition. Instructions are available here.
2. Copy en.stm32cubef4.zip from Sandbox (\\fsvs01) to your local direction somewhere.
3. Unzip the folder in the directory of this repository.

Flashing your board

The order of commands are described in instructions_to_load.txt in this repository

1. Open OpenOCD by running your edited bash file with bash openocd.sh
2. Open GDB by running your edited bash file with bash gdb.sh
3. In the GDB terminal, connect to the chip, select the binary file you compile, and enable semihosting (so that you can use printf) by running source gdb_src
4. Enter load to load the program onto the STM32 chip.
5. Enter c to allow the chip to go ahead witht the program. You can find more detailed OpenOCD commands here.

This makes a good and economical programmer when you don't have a dev board with ST-Link.

IMPORTANT:

You need to configure your file/folder placements exactly as described because all path in CMake.list is relative.

The order in which you open OpenOCD and GDB matters
