avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
error once again >:( so i was wondering if anyone could run by the possible solutions in case i missed any. I have the Arduino pro mini 5V 16Mhz. I have the Arduino 0017 software version, which i think is the latest.
The strange thing is that this chip wasn't workin when i got it (the not in sync error) then it worked once i downloaded the 0017 version and used the Duemilanove 328 board programmer. I put the chip into my robot a couple weeks later and now it gives me the not in sync error again.
Iv'e tried trouble shhoting it myself but i havent changed anything. if anyone knows what i can test (with a multimeter) or check (chip, programmer) or change (baud rate, board) that would be greatly appreciated
What serial interface are you using. It sounds like the auto reset on the RTS line isn't working or isn't connected. Or possibly the serial interface is not operational. Which one are you using?
I've tried changing the baud rates (19200 & 57600) and the board programmers (duemilanove 328, lilypad 328) and its still not working. While trying to dowload it i noticed that the tx LED on the FTDI breakout blinks red 3 times in a row then blinks once again later.... could somethinhg be wrong with either the breakout or the arduino? how would i find out?
Did 'rx' and 'tx' leads get switched around?
Go to your PC's control panel > system > device manager. Go to Ports(COM &LPT)[/color] , click on the + in front to see which USB Serial Port(COM ?)[/color] that your ckt is connected to, or if it is connected. I think it needs to be in COM4 or higher.
Click on USB Serial Port(COM ?) > Advanced In the resulting window you will see how to change the COM ports. Sometimes those COM ports get mixed up; you might be on one that shows that it is in use. Sometimes if you disconnect the USB cord for a couple of seconds, then reconnect, the ports will realign themselves. Do this while you are watching the device manager.
PO'T
I went into the USB Serial Port(COM ?) > Advanced and found one that wasn't in use. I also changed to the correct baud rate. I disconnected and reconnected, but its still not dowloading to the arduino without the not in sync error. By the way, when I first plug the FTDI USB thing into the USB cable, the RX LED blinks green and the TX LED blinks red. Does that have anything to do with it? Thanks for the help!
Hey jus wondering, in the Device manager, is there any other options i need to change? Theres bits per second, data bits, parity, stop bits, flow control, USB transfer sizes, latency timer, timeouts, serial enumerator, serial printer, anything that needs specific settings?
