When I try to uplaod to board I get the following error
avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
Also when my board is plugged in the power light shows on but the "L" light doesnt light up when reset is pressed. Is this something to do with the bootloader?
Run a loop back test (search the forum for details) to confirm that your PC to arduino USB serial channel is functioning or not. That error means the PC and arduino board are not communicating.
Thanks lefty, I have tried the loop back and it seems to work although the values returned appear to be the corresponding ascii values to whatever i put in.

Not sure what that means? During a loop back test, if using the serial monitor, if you type and send the letter A you should see the letter A printed back in the serial monitors receive window. Anything else implys a problem of some kind.
on closer inspection its chucking out random characters on some keys and nothing on others. I have connected the reset pin to earth and pins 1 and 2 to each other. I could only find one vague ref to the loop back test, i'm assuming this is correct.
Im guessing this is a general error rather than a specific one. Do you think burning the loader onto the chip again or replacing the chip would help?
