I have an Arduino UNO that I bought a year ago and have used numerous times. After doing other projects for the two months I came back to it last night.
When I tried to upload a bit of code I got the error message:
"avrdude: stk500_recv(): programmer is not responding
I tried with different bits of code and this kept happening.
I've looked at similar threads about this error but my situation is slightly different from most of them and I wasn't able to get a good answer from any.
The difference is that most of the people with this issue have brand new boards that never worked while mine has previously worked.
BTW, I have an iMac on ShowLeopard
Can someone point me to the cause of this error? Is the source in the arduino, the IDE, or the computer?
Forgot to go through that checklist of information to tell yea guys.
Yup, I'm positive that I had the right SerialPort and Board. Those are the first things I checked.
The first time I tried (when I got the error) I had a RFID sensor attached but disconnected it to do the troubleshooting once I realised that it wasn't a coding error; (I checked the board using a simple sketch to verify that it definitely wasn't my code).
I also double checked to make sure I didn't have anything else running (ie. Processing (which I did have on at first but turned off to troubleshoot)). I also made sure that something else wasn't using the USB port.
impolex:
If what you mean by echo back is that the RX light turns on whenever if is sent to the arduino...
"RX light" is neither mentioned in my post nor in the post referenced by the link. Why would you believe anything involving an "RX light" is what I meant by a loop-back test?
I have the same problem, but mine also blinks led 13 rapidly on power up, and when powered by a wall adapter. Board select is correct, serial is port correct and it won't let me upload a new sketch. I put the same atmega328 chip in my other Arduino, and it does the same thing. Any suggestions is welcome!
The good news is that the board itself is probably OK. The bad news is that the processor is toast.
There have been reports that the bootloader can become corrupt. If you have a particular fondness for the processor, I suggest trying to re-burn the bootloader.
I hooked the two boards together like it says on this site and when I clicked burn with AVR ISP it said it couldn't start the burn and the ledpin 13 kept rapidly blinking. Maybe I should have tried the another burn choice, but that's what the instructions said.
I tried to burn it again from the "use arduino as isp" link in the Examples section on this site again, and this time I choose burn w/Arduino as isp and it worked. Thank you very much for your patient help. If it wasn't for you, I probably would have bought another chip.
