Afternoon folks
I've hit a stumbling block with my project - I was planning on moving the project from my Arduino Uno to Arduino Nano to save space.
When i've used my nano, however, it worked to upload to it twice (I think. No success though - i attributed that to my poor coding) and have now noticed it is producing the below error:
avrdude: stk500_getsync(): not in sync resp=0x00
When I hold shift and upload I am getting:
avrdude: usbdev_open(): did not find any USB device "usb"
I am on a Win 7, 32 bit build - I've tried all the usual stuff; checking COM ports, ensuring the correct board is selected, uninstalling and reinstalling drivers (following this guide: http://www.circuitattic.com/home/5-site-news/2-nanodriverfix.html ) , all to no avail. The Nano is being recognised in the device manager ( USB Serial Port (COM6) in the port lists, and as a USB Serial converter in the USB device list.
Also noticed no light activity when the reset button is pressed, and on an attempted upload all I'm getting is 3 paltry flickers of the Rx LED.
I really don't know what to do - I've read it may be a corrupted bootloader but I don't fancy attempting to flash bootloaders and the likes unless absolutely necessary as I have no idea what I'm doing on that front.
Any help or advice would be greatly appreciated - thank you for reading!
Hey craighissett,Believe me,
Hey craighissett,
Believe me, you are not alone. I am facing an exact same problem with one of my Arduino clones ( an Atmega168 ). The usual stuff didn’t work out. I also tried flashing the bootloader, and it didn’t work at all. I am now suspecting the IC itself to be damaged or something. But unless you try and flash the bootloader, I wouln’t confirm that on your part.
Thanks buddy
Thanks Enig - I’ve just read a forum post by OddBot discussing using Arduinos to flash other bootloaders etc, and he mentioned a that drawing too much from the 5v line for too long can result in corruption; I foolishly had a servo or two attached and may have done exactly that. I will have a look at reflashing it tomorrow and hope for the best 
Reflashing Bootloader not working!
Having a rotten day today.
- I’ve uploaded the ArduinoISP sketch to my Arduino Uno
- I’ve wired the Nano’s ICSP to the Uno’s Pins D10-12, 5v and GND following OddBot’s guide
- Plugged USB cable into Uno - both powering as expected
- Left the COM port as my Uno (COM9), changed the board to Arduino Nano w/ATMega328, changed the programmer to Arduino as ISP
- Clicked Burn Uploader - had a variety of avrdude errors
My favourite so far:
avrdude: Yikes! Invalid device signature.
The most common:
avrdude: stk500_program_enable(): protocol error, expect=0x14, resp=0x50
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
Even had a return of:
avrdude: stk500_getsync(): not in sync resp=0x00
Any suggestions at all would be greatly appreciated.
** The exact thing(s) that**
The exact thing(s) that happen(s) to mine… I’m going with 6677’s “chucking the nano in the box” idea… 
ha ha!
It’s looking very tempting now ha ha! I’ve even designated a box ready to throw it in ready
