Dear I have a gumstix connex 200xm together with the wifistix and a tweener board. I have those connected and powered by 2 X 1,5V batteries to the wifistix board, the green lights go on and everything seems to be working. But then when I connect the board to my laptop using a the serial null modem cable together with a USB>Serial converter, I receive no data whatsoever when I connect to my serial port. I thought maybe I had to set the power to the tweener board instead of the wifistix board (although it should power both) but indeed that didn't help. All the settings are put in as it should and double double double checked all of them. I'm thinking that maybe 3V in total isn't enough? Or that my tweener board just has gone down, as I never received any data/ got console access. Any other suggestions, to eventually test if my Tweener is really broke ?

The absolute minimum required is 3.45v (3.3v + 150 mv headroom for the LDO). Using 3 alkaline (1.5v) or 4 NiMH (1.2v) would be recommended. Using the 4v wall wart would be recommended. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Powered it onto the wifistix, and waited for data to come up my terminal screen, but no ... still no messages or sign of Gumstix booting. I tried then to put the power onto the tweener board, which didn't make any difference at all. My USB>Serial cable should be fine and I'm starting to think the tweener board is broke. Other then the fact I don't get any console access everything looks fine (Green lights, no weird smell, ...). But without the console access I'm doomed, since I can't initialize a wireless connection to my laptop. Any other ideas are welcome.

Thanks for the reply. I increased the power with one battery of 1,5V which makes a total of 4,5V (alkaline batteries). Powered it onto the wifistix, and waited for data to come up my terminal screen, but no ... still no messages or sign of Gumstix booting. I tried then to put the power onto the tweener board, which didn't make any difference at all. My USB>Serial cable should be fine and I'm starting to think the tweener board is broke.
