Com problems again

Post by richile »

I had the stepper motor running fine. Disconnected motor to check resistance then reconnected. Did not run and then I tried to ulpoad to board (several times) when I received this error:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding

I have not changed the usb (checked it) tried all of the other trouble shooting suggestion, also quit app and restart computer to no avail.

Any possible resolutions?

Sounds like the chip got corrupted - easy to do when connecting various loads to pins.

Have you got a programmer to re-flash the bootloader?

i would unplug the motor shield
power down, then make sure you're powering the board properly
and try again

No programmer should I get a new AtMega? Where do I get the bootloader from?

never heard of a motor frying the bootloader so im wondering whats up. regardless you can burn your own bootloader if you have a chip programmer or i have them in the adafruit.com shop

I have ordered a new ATMega. They are already burned with a bootloader, right? I thought that this might be a less expensive solution. Do you think that this will work?
