THIS PAGE IS CURRENTLY UNDER CONSTRUCTION

Necessary equipment

  1. CutiPy

  2. 1 Micro-USB cable

  3. A pair of needle nose pliers for wire jumper re-positioning

  4. A personal computer (Windows or Linux)

  5. EMAC's latest MicroPython firmware release


Windows Users

  1. With the USB disconnected and power removed, carefully use a pair of needle nose pliers to shift jumper JB2 upwards from FLS to to RXM (The BT0 and RXM pins will now be linked).

  2. Connect your CutiPy to your PC using the Micro-USB cable.

  3. Download and install Zadig

  4. Open Zadig and select STM32 BOOTLOADER and WinUSB

    NOTE
    The STM32 BOOTLOADER option is only available when the microUSB is connected.


  5. Click Replace Driver



    NOTE
    Upon clicking “Replace Driver” the app may read “Not Responding” for a short duration and then recover. This is normal.


  6. After successfully installing the WinUSB driver, download the latest dfu-util application zip file here.

  7. Extract the zip file.

  8. For convenience, save the CutiPy firmware dfu file to the dfu-util folder.

  9. Open the Windows Command Prompt by searching and selecting "Command Prompt" from the Windows start menu.

  10. From the Command Prompt navigate to the dfu-util directory. If necessary switch drives by entering 'drive_name:. For example to switch to the C drive enter c:. Use dir to list sub-directories and use cd directory_name to navigate to a subdirectory.

    C:\Users\MyUser\Desktop\dfu-util-0.9-win64>



  11. Once in the dfu-util directory enter dfu-util -l. Something similar to the following should be displayed:

  12. From this directory install the firmware to the device by entering the following into the Command Prompt, where firmware.dfu is just the name of the firmware dfu file:

    C:\Users\MyUser\Desktop\dfu-util-0.9-win64>duf-util --alt 0 -D firmware.dfu



    NOTE
    If the firmware dfu is save anywhere other than the dfu-util folder, the full path location will need to be entered. E.g. dfu-util --alt 0 -D ...\firmware.dfu, where "..." should be filled in with the directory path.


    Something similar to the following should be displayed.

    C:\Users\MyUser\Desktop\dfu-util-0.9-win64>duf-util --alt 0 -D firmware.dfu

    The firmware is now installed.

  13. Safely eject and disconnect the USB, shift the JB2 pin jumper back to the original location (BT0 and FLS should now be joined). Now reconnnect the MicroUSB cable.

    Installation is now complete complete.


If desired, please enter a name for this project, otherwise press Enter to use the default: hello_emac

Linux Users

Follow the EMAC DFU instructions given here


After Installation

After installation of the firmware you can open a micropython REPL(read evaluate print loop) console (covered here ), and verify the firmware version by entering the following into the REPL console

>>> import os >>> os.uname()

Output should look similar to the following:

(sysname='pyboard', nodename='pyboard', rlease='0.0.1', version='394ae277 as IOT-F40
7C-XXXRX on 2019-06-07', machine = 'EMAC-CutiPy with STM32F407') >>>
