-- I NEED HELP PLEASE (updated 13 november 2006)
using information from Hans (thanks again), I was able to get power to the atmel.
- I can measure 4,5V between pin 1 and 2 of the atmel processor
- voltage regulator is heating.
BUT, I'm not yet able to communicate with the processor using serial cable.
What I know:
- As I own a v3.1, it looks like I can't use EC18-pin14, 15, 26. So I did as written in this guide: http://vems.hu/www.vems.co.uk/VEMS/ConnectingToSerial.html
- My cable works, I measured resistance between DSUB9 and board socket
- Here is a picture of my board now. Don't pay attention to "free" wires.

Here come the questions:
- Do you have any idea about what is missing?
- Do I have to solder more components?
- Do I have to upload firmware?
- I've looked at this page: http://www.atmel.com/dyn/resources/prod_documents/doc2467.pdf , and on my board pin 1 is at 4,9V(PEN), so I won't be able to upload anything, right? Is there a missing component?
- Was the card initialy loaded with a firmware?
Thanks for help

old stuff since here (solved problems)
- I'm sure I'm using the right pin for the RS232
- I don't get any signal in megatune
- as I can see ATM128 is not powered, at least I don't have 3,3V between pin 1 and 2 (in fact, there is no voltage)
Here is how pin are connected now:
- to battery -
- EC36-pin5
- EC36-pin21
- EC36-pin26
- EC36-pin32
- connected to battery +
- EC36-pin25
I'm not sure I have the good pin layout as I'm using the v3.1 board. Could someone confirm that? (especially for the EC36, as I don't have any power on the atmel processor).
I would really appreciate to know if I'm right with the battery + connected to EC36-pin25. As I can see, this pin doesn't go further on the board. I mean, there is no track from where I soldered the cable.
-Yes, battery + (12V) should be connected to EC36-pin25, but see also the following link to see how to mount the power on board..Hans .. http://vems.hu/www.vems.co.uk/VEMS/ConnectingPower.html
Thanks a lot, I'll try this. Bus as I can see on the picture on the page from phattransmission, my board has not the same components. Of the inductor between 1 and 2 and the fuse link between A and B are missing, but other components are not on my board. Do I have more components than the 2 to solder? (I'm not talking about coil/injector drivers)
The inductor from Rescue kit1 marked 1R5 must be soldered Between A&B, and just a wire (short) betwen 1 and 2 if a fuse is mounted external. The inline diode and the voltageregulator (top-left corner of first pic) should bee mounted when you got the board. I think that is it, hope it helps. Hans
Battery is ok
My com port are working fine - tested with dos:

My serial cable is ok
What should I test next? I'm afraid I made a mistake...
