Nano upload issue

Development Tools Uploading
1

I purchased two Nanos from arduino.cc and neither will upload now, however I did get the blink program to upload the first time, but not after that.

I have set the board type to 'Arduino Nano' and the processor type to 'ATmega328P'. Also set the COM port.

I get the following messages from avrdude:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xc2
avrdude: stk500_recv(): programmer is not responding

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I've tried pressing the reset button before the upload with no success. I do notice the rx led blinking 3 times when avrdude tries to upload. I also see the rx light blink once every time I receive an attempt message.

I am running on a Windows 7 home premium laptop.

Thanks for any help!

Also set the COM port.

Try again after updating the device driver -- Device Manager ----> Ports -----> USB-SERIAL CH340 (COM11)-----> Update Driver Software... -----> Browse my computer for driver software ------> Let me pick from a list of device drivers on my computer -----> select USB-SERIAL 340 ----> click on next

Are you using the latest AVR board package? If so, there should be an option for "Old Bootloader" under processor. If that is present, maybe you have boards with the old bootloader, so try that option.

If that isn't present, you're not using the latest version of the AVR board package (so all nano uploads use the "old bootloader" setting) - but you might have nanos that use the new bootloader. Upgrade the avr board package using board manager, and then try.

I downloaded the update for the board and I can now upload sketches. Thanks!
