No functionality change is intended with this commit, it just consolidates the separate implementations of GC helper code to the lib/utils/ directory as a general set of helper functions useful for any port. This reduces duplication of code, and makes it easier for future ports or embedders to get the GC implementation correct. Ports should now link against gchelper_native.c and either gchelper_m0.s or gchelper_m3.s (currently only Cortex-M is supported but other architectures can follow), or use the fallback gchelper_generic.c which will work on x86/x64/ARM. The gc_helper_get_sp function from gchelper_m3.s is not really GC related and was only used by cc3200, so it has been moved to that port and renamed to cortex_m3_get_sp. |

Build Instructions for Teensy 3.1
Currently the Teensy 3.1 port of MicroPython builds under Linux and not under Windows.
The tool chain required for the build can be found at https://launchpad.net/gcc-arm-embedded.
Download the current Linux *.tar.bz2 file. Instructions regarding unpacking the file and moving it to the correct location as well as adding the extracted folders to the enviroment variable can be found at http://eliaselectronics.com/stm32f4-tutorials/setting-up-the-stm32f4-arm-development-toolchain/
In order to download the firmware image to the teensy, you'll need to use the downloader included with TeensyDuino. The following assumes that you have TeensyDuino installed and set the ARDUINO environment variable pointing to the where Arduino with TeensyDuino is installed.
cd teensy
ARDUINO=~/arduino-1.0.5 make
To upload MicroPython to the Teensy 3.1.
Press the Program button on the Teensy 3.1
sudo ARDUINO=~/arduino-1.0.5/ make deploy
Currently, the Python prompt is through the USB serial interface, i.e.
minicom -D /dev/ttyACM0
TIPS
Install 49-teensy.rules into /etc/udev/rules.d
If you install the 49-teensy.rules file from http://www.pjrc.com/teensy/49-teensy.rules
into your /etc/udev/rules.d folder then you won't need to use sudo:
sudo cp ~/Downloads/49-teensy.rules /etc/udev/rules.d
sudo udevadm control --reload-rules
Unplug and replug the teensy board, and then you can use: ARDUINO=~/arduino-1.0.5/ make deploy
Create a GNUmakefile to hold your ARDUINO setting.
Create a file call GNUmakefile (note the lowercase m) in the teensy folder with the following contents:
$(info Executing GNUmakefile)
ARDUINO=${HOME}/arduino-1.0.5
$(info ARDUINO=${ARDUINO})
include Makefile
GNUmakefile is not checked into the source code control system, so it will retain your settings when updating your source tree. You can also add additional Makefile customizations this way.
Tips for OSX
Set the ARDUINO environment variable to the location where Arduino with TeensyDuino is installed.
export ARDUINO=~/Downloads/Arduino.app/Contents/Java/
Search /dev/ for USB port name, which will be cu.usbmodem followed by a few numbers. The name of the port maybe different depending on the version of OSX. To access the Python prompt type:
screen <devicename> 115200
