Hi!
i am playing with 2 arduinos UNO R3, in windows 7 machine, each one connecting to the other, all simple things... I am also using IDE 1.0.2. Yesterday i was uploading just fine with no errors whatsoever.
Today not one but two messages, on both arduinos from that 'avrdude' guy : stk500_getsync(): not in sync: resp=0x00. I checked Tools > PortT and Board and all according to my setup. I went to the troubleshooting and i had no luck finding a solution.
After some research i also found how to write the bootloader with ArduinoISP. Luckily I had a 3rd Arduino UNO so i tried and was SUCCESSFUL....but the second arduino just keeps giving the same message "avrdude: stk500_getsync(): not in sync: resp=0x00".
I checked and triple checked this setup: http://arduino.cc/en/Tutorial/ArduinoISP/ and i also changed wires in case 1 was doing bad contact.
a couple of things i noticed:
- The LED is brighter than on the the arduino i want to bootload...all the time.
- when i hit reset on programmer's arduino, the one that i want to fix also resets when USB cable is ON on both. This doesn't happen when only the programmer is ON.
- Soemetimes the message given is the subject of this message , other tmes:
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
The only thing i read about is to write through parallel port but i don't have 1 available...any solution?
Thanks in advance
