i know that there are already a lot of these issue (avrdude: stk500_getsync(): not in sync: resp=0x00) solutions spreaded on the web, but i read the troubleshooting and fighted through a lot of entries and haven´t found the right one yet.. so i hope one of you guys have maybe a specific solution.. :)
it worked yesterday and isn´t anymore since today.. i tryed a different circuit (#10 from vilros) when it "happend", but i don´t think that the issue is here.. nothing is working now, not even the easiest circuit (read somewhere that a wrong pin use can also "disconnect" and evoke this issue).. i guess it´s not the code or the circuit!
i tryed it with multiple usb deviced on win 8.1 (64bit) and win 7 (64bit). based on the troubleshooting thread, the bootloader should work (led is blinking). but he isn´t finding the usb #3 on win 8.1 anymore with the ide.. = it was also plugged in usb #3 when it ceased working.. there i get a "avrdude: usbdev_open(): did not find any USB device "usb"".. so he isn´t finding usb# 3 in win 8.1 and is´t working with the other plugs.. and is also not working with any usb plugs from win 7 on a notebook..
ide = 1.0.5 - arduino uno r3 and yes, i got the right board :)
havent had the possibility to check it with another usb cable..
maybe one of you have an idea?
