We ordered a couple of boards (Waters), which arrived yesterday; one worked fine but the other failed exactly as you describe. A quick test proved that it could still boot from microSD, to u-boot at least. Haven't tried yet for a full Linux boot.<br> <br> <br> Michael Groufsky<br> <br> <br> <br> richard dorfner wrote: <blockquote cite="mid:681...@ma..." type="cite"> <pre wrap="">That bit of 'garbage' at the begining is teh serial boot loader trying to see if someone is out there to give it an image. it's POSSIBLE that your terminal might be locking up or refusing to display anymore data once it gets that burst and then not seeing any further data. However, I have not had issues with this myself using kermit to connect to the overo. what system are you using to connect to it? a linux box? a windows box? what program are you using to display the data on your listening device?

For my first test my goal was simply to get connected to the console on the gumstix. I plugged the overo into the board followed by a USB cable to the console port. I connected to the new serial port with the appropriate settings but only got garbage when I powered up or reset the board. Using a scope I verified that there is data coming out of the gumstix at 115200 baud. Looking at the hex I can see the following: 04 01 05 05 A3 06 74 D8 B5 62 81 01 00 24 55 16 0C 20 40 00 00 00 01 04 08 20 40 00 00 00 01 04 08 20 40 00 00 00 00 51 54 2C 30 40 00 00 00 01 04 08 20 40 00 00 00 01 04 08 20 40 00 00 00 01 04 F8 00 This seems to be consistent after each reset so it is probably more than just line noise. I have also confirmed this watching the TXD3 line with another device. I check the following supplies on the palo43: V_batt=5.1v VCC_1.8=1.79v (only when gumstix is installed) VCC_3.3=3.3v So the supplies seem to be okay and nothing gets hot. The main processor on the overo gets slightly warm if it has been powered up for a while. Also when I power the board up D2 on the overo lights as well as D2 and D3 on the Palo43. I also connected the LCD and powered the unit up. The backlight came on, but nothing was ever displayed. What might be the cause of these problems? Am I just a fool? As I understand it the overo should come with a preinstalled boot image. -- View this message in context: <a class="moz-txt-link-freetext" href="http://www.nabble.com/Overo-fire-DOA-tp25445191p25445191.html">http://www.nabble.com/Overo-fire-DOA-tp25445191p25445191.html</a> Sent from the Gumstix mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Come build with us!
