not in sync

Homemade Arduino board not in sync with Arduino IDE

Hi,

I flashed a blank Atmega328 chip with an AVR dragon lended.

That chip was running nicely on the breadboad it had been flashed on.

I could program it with arduino IDE, through a uno board without it's chip.

Then I built a small board for that chip.

The program (blinking LED) is working properly, but I can't reprogram it with arduino IDE anymore.

I got the message :

"avrdude: stk500_getsync(): not in sync: resp=0x00"

 

Sparkfun FTDI Basic fix

Like another user on the forum, I had problems with my FTDI cable and I couldn't program my Arduino at all. It used to work flawlessly, but suddenly it stopped working all together. It's recognised by the computer and by the Arduino IDE, but whenever I try to upload a sketch it displays the "not in sync" message. However, it works if I plug the FTDI cable into the computer, then click upload, and at the very moment when the IDE displays the sketch's memory info I plug the cable to the Arduino.

Hope this helps
