Hi, I am a new, totally green user of the Overo Water. In other words, I'm pretty lost on even the most basic programming. I'm an engineering student at the University of California, San Diego, and I'm trying to use the Overo for data acquisition in a senior project. However, I can't even get the thing to boot up. I have the Overo attached to Summit board, and when I connect it to a monitor and turn everything on, I get a loading bar that freezes about halfway across. I suspect something might be up with the operating system on the SD card, but I don't know how to reload it. I've tried following the "getting started" instructions on the wiki, but I'm totally lost. Any help would be most appreciated.

Hey =) Just wait longer =) the first boot takes quite a while,because everything has to be installed... just plug the serial consol in and have a look what the thing is doing.

Thanks Bernhard, that was exactly the sort of tip I needed. I did play around with the micro SD card a bit before I tried booting the Overo again though. I used windows to reformat it and then just moved a few zip files onto it (DSL and some other file that the website said it needed). I don't know if that did anything, but I can see something on the screen now. So, any clues about how to go about getting some from the thing? My project is a surfboard with sensors embedded into the foam. I want to read voltage outputs from all the sensors using the Overo with a pinto expansion board. Right now I'm using the Summit to explore the Overo. I'd like to use Python to handle the DAQ code, but I have many questions and concerns such as: At startup, can I just flick a switch to make the Overo start reading data, or do I need to hook it up to a monitor for each data sampling session and enter some commands? How do I get Python onto the Overo? How to I even write Python code that handles data acquisition? What sort of battery will I need? As I said, I have literally no experience with Gumstix, and my understanding of programming is like that of an infant.

Not using python for reading the adc's but using it for bluetooth and wifi scanning. To get code or programs started on boot, add your own init script and call the program from there. Note that will start it on every single boot. Would be vey easy to 3g/gsm enable it using an E160 gsm modem (also start it from an init script) and have it log to the cloud or web server or service like pachube or a database somewhere. I posted an init script a few months back as have plenty of others , have a search in the archives.

Ok, I tried opkg update and opkg install python python_modules and I only got error messages. How to I access Python from the command terminal? This might lead into another question I had, which is how do I use my PC, which is running windows, to put files onto the overo. My computer has a Micro SD card slot. Could it be as simple as dragging files from my desktop onto the SD card?
