Known Issues

Recent updates to the gcc-arm-none-eabi compiler seems to break all of our code. The last version we know that works with the code is release 5.4.1 20160919.

Preparing Your Workspace

Requirements (TODO: try python3 and update this readme):

Install pip using python2 and script that can be found online: python2 get-pip.py

Install mbed-cli:

pip2 install mbed-cli==1.0.0

Clone:

Using mbed-cli:

mbed import git@github.com:ANRGUSC/m3pi-mbed-os.git
cd m3pi-mbed-os.git
mbed toolchain GCC_ARM
mbed target LPC1768

Using git:

Initializing mbed project after cloning this repo:

git clone git@github.com:ANRGUSC/m3pi-mbed-os.git
cd m3pi-mbed-os
mbed deploy
mbed new .
mbed toolchain GCC_ARM
mbed target LPC1768

Install Pre-reqs (also for debugging):

1. Upgrade firmware of the mbed https://os.mbed.com/handbook/Firmware-LPC1768-LPC11U24

2. Install python packages: pip install -r requirements.txt

3. Install python, libusb and libncursus (i386 to be compatible with arm-none-eabi-gdb)

    sudo apt-get install python libusb-1.0-0-dev libncurses5:i386
   

4. It might be necessary to update your USB settings to get non-root access to DAP:

    sudo sh -c 'echo SUBSYSTEM==\"usb\", ATTR{idVendor}==\"0d28\", ATTR{idProduct}==\"0204\", MODE:=\"666\" > /etc/udev/rules.d/mbed.rules' 
    sudo /etc/init.d/udev restart   
   

Run Instructions:

By default there is no main.cpp and thus the mbed compile command will NOT work. To run a app, use the provided script load_app.py. You can directly compile and load a particular app by using load_app.py e.g., python load_app.py app_files/hdlc_test/. Please note that the load_app.py will not work if there is no existing binary inside the LPC1768's USB mass storage memory. After an mbed compile -c, there will be a BUILD/LPC1768/GCC_ARM directory which will hold the binary.

Alternatively, to run a particular app manually:

• Go to the app folder under e.g., app_files/hdlc_test/

• Delete .mbedignore file in that folder

• Now you can use traditional mbed compile -c to compile the code

• After you are done, you can put back .mbedignore available from app_files/ignore_file/
