Why can't I upload a sketch?

I can not get my to accept a compiled script.

My got my board second hand. It is not too old. It has a 2007 date silk screened onto the board. I have included a photo of my board and one of a company called "NKC Electronics". The boards look alike. I have also included the schematic. It appears from the schematic that it should support auto-reset.

The processor is an ATMega328 and I burned a bootloader to it.

Testing I have already performed.

  1. I removed the processor and placed a jumper between digital pins 0 and 1. Opened a terminal and typed. Everything sent came back. Tested speeds for 300-115K
  2. Manually reset the board. In case the auto-reset was not working.
  3. Moved the chip to a Duemilanove. To make sure there was not a problem with the bootloader.
  4. If I load the sketch on a different board, it runs fine when the chip is moved to this board.
  5. I have the correct comm port selected.
  6. Turned on Verbose upload and received:

avrdude done. Thank you.

I have the board "Arduino Duemilanove w/ ATmega328" selected since that is the bootloader that is on the chip and most closely matches the board.

On your board C10 looks like a diode (glass package). Is that intentional?

We have a winner. Why someone thought that a diode would work better than a capacitor, I do not know. Like I said, I got this one "second hand". The rest of the construction looked pretty good.

They are spelled about the same, so it is an easy mistake to make. :slight_smile:
