Hi, I am new to gumstix, and excited to receive my first toy, it is an Overo Earth with a Tobi expansion board. However, when I follow 'Overo: Setup and Programming' 'Getting Started' instructions, I was only able to use kermit to connect to /dev/ttyUSB0, but not be able to power it on after connecting the power. No boot messages and no extra LED illuminating on the board. I did some search and found that an announcement was made from gumstix that: after June 8th, 2009, all Tobi boards are shipped as r2441, but mine is r2411, could this be a problem? I ordered my components only a few days ago (around June 20th), any help is appreciated. Cheers, Feng |

Hi Feng, Search for "booting from SD" within the forum and you will find answers. I am having the same problem. If I get it resolved I will let you know what I did.

Check to see of the Overo COM is seated properly in the Tobi. If there is interference, power may not be getting from the Tobi to the Overo.

My friend has the same set of boards and both of us have the same issue. We double checked connections between Tobi and Overo COm, both seem connected properly. Stuart, I will check SD card option tonight. On Thu, Jun 25, 2009 at 5:42 AM, anon4321 <ano...@co...> wrote: > > Check to see of the Overo COM is seated properly in the Tobi.

That chip is powered by the USB bus power. The fact that you get no power LED on your Overo means there is an issue with the power supply. What are you using for a power supply? If a wall-wart from Gumstix, check to make sure that it takes the proper input voltage for your area of the world. It should put out 5V - measure with a DVM to make sure!

Hi Stuart, I found it was connection problem between two boards. The spacer is too thick. You need to make sure that Overo sits on Tobi tightly enough.

To be precise, you do need spacers between two boards. I bought $4.0 spacer kit from gumstix. There are three sets spacers, one white, two blacks. Choose the thinest black one. Initially I estimated the space between two boards is about the thickness of the white one (middle size) and that was the problem.
