This is a port of MPE-Lite for Cortex-M0 to the ST Micro SMT32F072R Discovery board. It makes use of the Sockpuppet layer for interfacing between the board-support layer (supervisor) and the application written in forth.

The supervisor is supplied in binary form, and can be re-compiled from source with GNU GCC for arm. See the supervisor dir for details

How to Install

• Install the MPE Lite compiler
• Clone this into the MPELight CortexLite Directory, along with the submodules:
  • git clone --recursive https://github.com/rbsexton/mpelite-stm32f0.git

Applications:

hello : Hello World. No features to speak of, just a prompt.

How to Build with Wine:

• Start Wine Shell.
• cd ./xArmCortexLite/CortexLite/mpelite-stm32f0/hello
• wine /xArmCortexLite.exe include STM32F072.ctl

Flashing images

You'll need some sort of tool for installing images via DFU.

For Linux and Mac, you can use dfu-util.

1. Connect the BOOT0 pin to VDD with a jumper and reset the board.
2. Remove the jumper. The board will stay in DFU mode.
3. Launch your dfu utility. Example: dfu-util -s 0x8000000 -a 0 -D STM32F072.img
4. After the board loads the image, press the reset button and connect to it with your terminal emulator.

Communicating with the board

The board supervisor contains a USB CDC driver and acts like a serial port. Connect to it with the terminal emulator of your choice.
