FTDI cable and ArduIMU+ (non flat) error (SOLVED)
I tried all the eight debugging steps, but the error persists.
My arduino board works perfectly with the latest FTDI drive, but with DIY FTDI cable I have this error:
So I will try to use an Usbasp AVR programmer to replace the bootloader with AVRDude.
It will require a "path-board" between programer and ArduIMU, because the pins order is different. But the worse part is the pin "D10"... what is it funcion?
On AVR programer I have this pins:
MOSI
VCC
RST
SCK
MISO
GND
On the ArduIMU+ there is:
GND
VCC
SCK
MISO
MOSI
D10 <---- ( what is this??? Is it mandatory for the connection with ArduIMU+?)
RST
Last question: Is the bootloader exactly the same that Arduino 328?
My spine is freezing... but I don't see another way to go.

SOLVED
It was solved by doing this steps over an AVR programmer.
(Is VERY important that you do the first step and check the result)
1 - Erasing the chip (make sure that "lock fuses" are changed to FF);
2 - Setting the other fuses by this way:
low_fuses = 0xFF (bits 11111111)
high_fuses = 0xDA (bits 11011010)
extended_fuses = 0x05 (bits xxxxx101, because only the three last bits are changeable) ;
3 - Recording the "ATmegaBOOT_168_atmega328.hex".

Ken, Mark and Morli. Thanks for reply!
I think the angle and shiny really don't helped. But, anyway, I soldered again for make sure. Nothing happen. The same error here. :(

Really better, but... :(

Check on top, near solder jumper by IC2 741xxx, make sure it only contact two pads, it may have a splash to pin 4 on IC2, shorting RX-in to +5v....

I checked. There is no splash. I'm thinking about to make a bridge bypassing the IC2, for testing the direct connection with pin 30 on ATMEGA 328. Do you know if I will burn out the chip with it? I think that it will be "innocuous", but maybe I need to open the VCC's jump.

OK!!! It's working now!!!
I tested the mix chip through a code that I sent to ARDUIMU+ with the AVR Programmer:
The code received and sent data over FTDI cable. It commuted the serial data flux on MIX chip by D2 output with a pre-programmed delay time. OK! Nothing is wrong with the board.
So... I cheked all again in avrdude ans saw some inconsistent data. I do all the setup's steps again: erasing all the chip, setting the fuses and recording the bootloader. OK!!! It finally worked.
I have noticed that, at the fist atempt, the "lock fuses" aren't changed. The value wasn't "FF" but "CF". Other thing that happens: the first program that I used (eXtreme burner) recorded weird bits on the extended fuses by the input value "0xDF" instead "0x05". Man... I'm so very... very... happy now!!! :D
Thanks for all the friends that helped me here! I'm very grateful.

Congrats! Now you really know that boot loader is working .. Cool beans

Thank you, Mark! ;)
At the start I was very bored... but now I can see that the challenge gave me some benefits.
I learned a lot of things because of it. Now I'm a little bit more prepared for the next one and I met some nice people. Very cool! :D
