I have an Arduino Uno and I am using arduino 1.0.5 IDE. I followed he procedures for bootloading an atmega328P-PU on a breadboard.

I uploaded the ArduinoISP sketch first, made the connections(using the External Oscillator) and then wired it up. Then, I selected the programmer as Arduino as ISP, selected the board as Arduino duemilanove w/ Atmega328P. Then I selected the correct serial port and clicked Burn Bootloader. I got the following errors:

avrdude.exe: stk500_program_enable(): protocol error, expect=0x14, resp=0x50avrdude.exe: initialization failed, rc=-1 Double check connections and try again, or use -F to override
this check.avrdude.exe: stk500_disable(): protocol error, expect=0x14, resp=0x51

How to solve this issue? Also, can I upload the bootloader directly by using it on the Uno in place of the original chip. If so, how?

  • This question is probably more suited for [Arduino StackExchange](http://arduino.stackexchange.com/) - it could potentially be a hardware problem – Levi Sep 27 '15 at 07:18

to my understanding the error you have indicates a bad reading from the chip. I experienced that with chips that were either dead or not properly connected, especially to power supply.

You may find more detailed information in th tutorial : https://www.arduino.cc/en/Tutorial/ArduinoISP

Especially those things :

  • Note for Arduino 1.0: you need to make one small change to the ArduinoISP code. Find the line in the heartbeat() function that says "delay(40);" and change it to "delay(20);".
  • Select the items in the Tools > Board and Serial Port menus that correspond to the board you are using as the programmer (not the board being programmed).

Instead of arduino built-in boot loader just go through below link and it will be great for uploading boot loader and verifying board status info

I am replying you this because same issue I got long back and it saved me.

One more thing for arduino boot loader: for atmega328 you need to put capacitor between reset and gnd( in case you missed)

For gammon bootloader you don't need it.

Be Innovative.

For reset line you might me using 100nf(thats what stated in documentation )...but sometimes it doesn't work...try something like 4.7uf, 22uf or 47uf or close values

I had a similar problem and the issue was that my programmer was a bit slow, I used the -B flag for avrdude to slow down the bitrate and it started working, I set the -B20 and works like a charm every time, but I use the USBTinyISP programmer, not the stk500 one, so this might not work for you.

In case someone stuck at this as I did and nothing like changing the cap value helped. Make sure you are using your USB-TTL adapter in a 5v mode (obviously for a 5v powered chip). I always used it in a 3.3v mode in order not to accidentally burn my 3.3v chips and it always worked. Until today, I was trying to flash my custom atmega8 board and everything worked with the ISP but I was having a hard time using the bootloader and after half a day searching and trying different stuff the 5v setting to the rescue.
