Hi Thomas, The problem is that in the latest revision of RoboVero there is a change to the IMU circuit. It's power is now under control of a LPC1769 GPIO. You can see the latest schematic here: http://pubs.gumstix.com/boards/ROBOVERO/R3902/ Someone put together a patch but seems to have forgotten to push it up and is on vacation this week. I haven't tried, but you should be able to get it working but pulling P1.0 low at the start of your program. Sorry about the error. We'll try to get upstream updated ASAP. - Neil On Thu, May 16, 2013 at 10:44 AM, thomasccp <tho...@ms...> wrote: > Hi Neil, > > The RoboVero board is R3902.
