POP-BOT Inex upload trouble

Hi,

We're using a INEX POP-BOT (with Arduino POP-168 -> Board have to set on Arduino Mini).
And suddenly, after fine using, it don't upload. Arduino gives the mean error: avrdude: stk500_getsync(): not in sync: resp=0x00 etc.

What happened?

The usb cable works fine, device manager gives no trouble, the POP-BOT itselfs works fine with the program that was upload at last. But it don't upload again.

Is there any manner to give a deep reset? Or have the pupils (we use them at school) faked the bootloader?

Anyone experience with this robot?

Sometimes a sketch sends out so much serial data that the USB buffers get flooded. To fix it:

  1. Unplug the USB cable.
  2. Hold down the Arduino Reset button.
  3. Plug the USB cable back in.
  4. Click on the upload button for the sketch.
  5. When you see the "Binary sketch size:" message in the sketch window, release the Reset button.

If that fails, buy an ISP programmer like a USBtinyISP or USBasp. That will allow you to re-write the bootloader and/or load sketches without a bootloader.

Works!
Fine, thank you.
