Hey,<div><br></div><div>Adam, Thanks for writing a ROS wrapper for the sparkfun razor imu.  It&#39;s actually something I was about to start working on.  However, I&#39;ve been banging my head against a problem installing your AVRdriver firmware onto the IMUs and I&#39;d appreciate any assistance you (or the community) might be able to offer.</div>

<div><br></div><div>Here is the process that I&#39;ve taken so far. Note that I&#39;m running the a fully updated version of cturtle on Ubuntu 10.04 Lucid (64bit).  </div><meta http-equiv="content-type" content="text/html; charset=utf-8"><div>

<br></div><div>1. Plug the IMU via an FTDI board into the USB port of my computer.</div><div>2. Open Eclipse and import an existing project into the workspace, pointing to /rutgers-ros-pkg/imu_9drazor/src</div><div>(I&#39;ve followed your AVR Eclipse installation instructions on the avr_bridge package documentation.)</div>

<div>3. Build the project.</div><div>4. Press the Upload current project to Atmel target MCU</div><div><br></div><div>The last step is where I run into a problem, and get the following console output.</div><div><br></div>

</div></div></div><div><br></div><div>I think the problem may lie in my selection for AVR Programmer.  I&#39;ve selected the Arduino from the Programmer Hardware (-c) option and entered in /dev/ttyUSB0 into the Overide default port (-P) section.  The Target hardware is set to ATMega328P with a clock of 8000000.  Do you use the same AVR programmer settings as I do?  Do you see anything else I&#39;m doing wrong in this process?</div>

<div><br></div><div>Thanks again,</div><div>--Will</div>
