I received my Gumstix and Robostix two weeks ago for my project this fall at the Norwegian University for Science and Technology (NTNU). The first thing I noticed was the weird dents on top of one of the chips on the Verdex XL6P. I don't know if they are normal, so I've attached an image of it. The other image shows how I've connected the Verdex to my computer. The Verdex is plugged into the Robostix, and the Verdex FFUART available from the Robostix is connected to my Atmel STK500 - which also powers the board with +5V. The STK500 contains a level converter and RS232 out which lets me connect it to my computer.
Using kermit I can connect to the Verdex, and at first it seems ok, but then it starts resetting. I've added a 10k pull-up resistor between pin 3 and 4 (RxD and +5V) on the Robostix, but it didn't help much. Now I'm wondering if the Verdex (or the Robostix) is damaged, or eventually what I'm doing wrong. I'm stuck at this before my project can continue. Output from the FFUART is also attached in a txt.
The Gumstix seems like a great little computer, and I'm looking forward to the day I get it to work. Any help would be appreciated. :)
Any suggestions is greatly appreciated!
