Hi there,

I have an arduino duemilanove and after a "normal" sketch-upload with no special commands (e.g. no direct port access)
the onboard LED 13 is flashing all the time very quick. After that, I had no access to the board anymore.
Pressing reset button has no positive effect.

What could that be?

Thx in advance.

What was your sketch intending to do?
Designing & building electrical circuits for over 25 years.  Screw Shield for Mega/Due/Uno,  Bobuino with ATMega1284P, & other '328P & '1284P creations & offerings at  my website.

Are you sure you have loaded the sketch? Were there any compile errors? Have you tried disconnecting and reconnecting the Arduino?

I build an own keypad an the sketch was simply checking the digital pins for HIGH or LOW-Level.
No direct port access. I tested the shield with the sketch on my UNO-board and it worked very well.
So I think, that's not the problem.

Could it be, that the bootloader was going corrupted?

The error message says:

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51


I dont' know whether the sketch was loaded completely. I tried many times disconnecting and reconnecting and reset button. No effect!
