New Gen7 build connection issues November 24, 2011 11:39AM |
Hello,
I recently received ( thx Markus) and assembled my new Gen7 board. The power checks went well once I found a solder bridge on my ATX24 connector. I installed the mosfets and atmega and followed the instructions on the wiki for configuring arduino for the board. I first connected power to the Gen7, as expected the board moved through the PS on, blinking light, PS off routine. Everything looks normal however, when I plug the unit into my usb port (win xp ) I get a series of connect/disconnect notices. It never settles on a port. In Windows 7 a port is assigned but attempts to upload anything to the board are met with some guy named avrdude telling me there is no connection.
Any suggestions on what to look at?
TIA,
Neil

@bryanandaimee
I did this several times throughout the adventure to no avail. I also reset the com port allocation list in registry at one point. All these symptoms occur on two different machines. Thanks for the help.
@VDX
Tried this as well, each time failed though
Thanks though.
I disconnected the FDTI card and watched what happened if it was all alone. Oddly enough it acted exactly the same way with no board. Weird though, I tried settings for the sanguino 644P and it acted like it was trying to upload. After inspecting my FDTI card I noticed that the #16 pin on the chip was shoved against the #15 pin. I tried to gently separate them but it #16 was broken off at the chip. So I have a FDTI cable on order from Adafruit and will try that when it gets here.
If I read the data sheet for the FDTI chip correctly pin 16 is a signal pin from the USB. D- or some such. If you hold the board with the USB connection on the top and facing you it was the pin that is farthest down on the right. I tried it after removing the pin completely and the behavior is identical. Could this have been the issue all along?

well you were right, the pins on the e-go board were wrong and I found the transmit pin in another place 
now the arduino says
Expected signature for ATMEGA644P is 1E 96 0A
Double check chip, or use -F to override this check.
I have selected [email protected] and the chip you have provided says 644-20PU so I assumed this is the right one, so I use -F ????
It worked correctly with [email protected] (no P)
if everything is ok , thanks for the help
