Hi again Drew,

I can't find anything relevant on Google with the search 'loopback test arduino mega 2560'.

Would you mind pointing me in the right direction for advice on how to perform a loopback test?

thanks again,





You have told the IDE that you are using the Mega and not the UNO, right?

Hi folks,

Thanks so much for your replies.

I've now tried the following things :

Confirmed that the IDE is pointed at the correct board.
Performed a loopback test - worked fine.
Tried pressing reset when the sketch size shows in the compiler - same result, timeout error.

The only suggestion I haven't tried is reinstalling the bootloader - I'm a bit nervous about doing this, so would like to explore any other possible solutions before going to this step.

I should also mention that the Mega seems to have installed correctly - it appears in control panel on Com 10 as 'Arduino Mega 2560 R3 (COM10)', and makes the familiar 'USB device plugged in' sound when plugged into my PC.

Please, if anyone has any other ideas as to how I can get this rotten board to work, I'd appreciate hearing them.

Thanks in advance.
