stm32f4-CANopen-project

An empty project with all the boilerplate to start developing with stm32f4 and canopen-node

Change the output file name in app/module.mk

Grab the project with: git clone file:///path/to/repo/

Cloning will bring over the remotes specified in that directory. So you'll need to remove the remotes you don't want.

git remote rm <remote>

And add the ones you do, after you have created your remote repository.

git remote add origin <url>

You will also want to --set-upstream-to, or -u to tell git this is the remote repository this branch will update to, presuming you are on the master branch.

git push -u origin master

Then you'll need to decide which branches to keep and add to the remote. If you want to push all of them, just do git push --mirror. This will push all your tags and your remotes. But since we edited your remotes in an earlier step, it shouldn't be a problem.

If you only want to keep a few, you can git push -u origin each one you want.

Install a few packages to make everything work

sudo apt-get install flex bison libgmp3-dev libmpfr-dev libncurses5-dev libmpc-dev autoconf texinfo build-essential libftdi-dev libexpat1 libexpat1-dev

Install the arm-gcc toolchain

The toolchain is here:

https://launchpad.net/gcc-arm-embedded

Find the link for the PPA and add to your system:

https://launchpad.net/~terry.guo/+archive/gcc-arm-embedded

sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
sudo apt-get update
sudo apt-get install gcc-arm-none-eabi

Download stlink to interface with the stlink programmer

Install stlink

sudo apt-get install libusb-1.0
git clone https://github.com/texane/stlink
cd stlink
./autogen.sh 
./configure
make
sudo mkdir /opt/stlink
sudo cp st-util st-flash /opt/stlink
sudo cp 49-stlinkv2.rules /etc/udev/rules.d
sudo /etc/init.d/udev restart 

Add /opt/stlink to your PATH and test out the st-util utility

st-util -h

Build the code

Run

make

to build the application code.

Use "make clean" to remove program build files. Use "make realclean" to remove library build files as well.

Load and execute an elf file with gdb

While your laptop is connected to the board via the debugger run

st-util 

Then reset the processor, open a new terminal and run

arm-none-eabi-gdb app.elf
target remote localhost:4242 
load
continue

Note that optimization settings can cause issues with breakpoints

Flashing a bin file to the program memory

While your laptop is connected to the board via the debugger run

st-flash write app.bin 0x08000000
