Program not uploading gives error

Things you need to know:

I used Arduino with motor shield and may have accidentally burnt the chip (as I had already burnt the l293d, supply was 12V 4.5Ah), after that program stopped uploading

  1. I have checked the port.

  2. Tried resetting

  3. removed the atmega328p and put it back again

and now I get this error:

Sketch uses 930 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

Even the blink.ino isn't uploading.

What is wrong here? Shouldn't I have removed the chip? Do I have to bootload now? Can I try bootloading the same chip?

Thanks :slight_smile:

Is the board recognised by your PC? If not, buy a new Uno.

Have you tried the loop back test? If it passes, it' likely that the 328P is toast. You can buy a new one with boot loader pre-installed.

If loop back test fails, buy a new Uno.

The board is recognized by the PC. Also the loopback test came back fine. I guess its the atmega then.

Thanks @sterretje :slight_smile: :slight_smile:

Do you uave anything connected to reset? That will interfere with uploads if so.

Im impressed that you managed to trash the '328p without trashing the usb interface - is it an official board, or a clone? (The clones with non-16u2 for usb serial seem to be more resiliant)
