Introduction

OpenSourceMID.org is founded by a group of engineers enthusiastic in
modern technologies and open source software development and sponsored
by Timll Technic Inc. in China. It is an open community to provide
support and discussions for K7 MID or any other open source MID projects
through this website.

OpenSourceMID.org, itself, is an Open Source project. This means, first,
that we offer not only a product but a process, and second, that we
depend upon the contributions of developers and endusers to make that
process happen. The easiest way for you to help us out is to join the
overall OpenSourceMID.org project by join OpenSourceMID Community.

How to use the USB device port as the UART debug port

1. Download the USB driver for Windows “Littleton USB Driver for
   Windows.rar”
   and extract it.

   1. Connect K7 to your computer’s USB port. Windows will detect the
      device and launch the Found New Hardware wizard. Vista/7 users need to
      cancel the automatic driver update.
   2. Select “Locate and install driver software.”
   3. Select “Browse my computer for driver software.”
   4. Click “Browse…” and locate the folder where you extracted the

   6. Download the Android SDK for Windows
      “android-sdk_r07-windows.zip”
      and extract it.
   7. Run the cmd in Windows.

   8. Enter the commands below:

      D:
      cd D:\android-sdk-windows\tools
      adb.exe shell

Now the USB device port is working as the UART debug port. You can
install applications from computer. Enter the command below:

  adb.exe install D:\AdobeReaderv10.0.0.apk

WinCE
