android-stm32-dfu-programmer

Brief Description

This app is able to mass erase a STM32Fx and flash it with firmware from a .dfu file. See the accompanying youtube video for a demonstration

android-stm32-dfu-programmer video

###Notes### The USB_VENDOR_ID and USB_PRODUCT_ID in the MainActivity.java file must match your STM32 device, otherwise the app will not recognize the usb device.

###Instructions###

  1. Create .dfu file with DfuSe by STM with the proper PID, and Version number. Note: Only one image per file is supported.
  2. Copy the file into the Internal Download folder of your Android device.
  3. Hold/Jumper Boot0 button/pin ( and sometimes also reset button) while connecting the usb device to the Android device USING an OTG cable.
  4. (Re)open the app. If device was found, the permission dialog appears. Allow persmission to access USB device.

Once your device info is displayed int the text field, you are ready to perform two actions.

  • Press Mass Erase Button to completely wipe the Flash memory excluding the Option Bytes. This might take 15 seconds depending on the Flash size and app will not respond until its finished.

  • Press Program Button: This will load the .dfu file from Download Folder and sent to attached Device. Once the file is downloaded it will automatically start the new program downloaded. If you want to Mass Erase, reconnect the cable and restart the app.

###Tested on### Nexus 7 (2012) running stock Android API 19 (Kitkat) connected via USB to a STM32-P107 Dev Board by Olimex

###Limitation### Only one .dfu file must be located in the internal Download folder. The .dfu file must be compiled using dfuSE version1 (tested with DFU File Manager 3.0.3) with at most one element file for at most one target. Does only mass erase the complete flash memory. The image file size must not exceed the target device flash memory capacity. Any errors during programming are ignored by clearing the status.

Known Issues

On some STM32F devices, It takes several tries to recognize the USB device.
