New Atmega328 chip

Other Hardware 3rd Party Boards
1

Hey,
I purchased two new ATmega328 chips. When I try upload a new program onto the chip it gives me AVR dude error. Also when I push the RESET pin nothing happens, the LED does not blink. I remember having a similar problem long time ago but I solved it by selecting the duelinove board instead of the Ardiono UNO which I currently have. These chips are brand new I doubt they broken. I have two UNO boards and none of the boards are respoding but my old chips ones are. Is there a setting I need to change. Also I get an avrdude error whilst trying to burn the bootloader, USB not in sync. Could the bootloader be the problem that it is not burnt onto the chip? or what else can it be before I go on mission and burn bootloader (Any other setting I can try)?

Kind Regards

Unless you bought the chip from someone who said it had the Arduino bootloader burned into it already you probably got one fresh from the factory with no bootloader. The easiest way to burn a bootloader is with an ISP device like the USBTinyISP or USBasp. You can buy one for less than the price of an Arduino.

You can also use the ArduinoISP sketch (File > Examples > ArduinoISP) to use one of your UNOs as an In-circuit System Programmer to burn a bootloader onto one of the new chips.

Be warned that the reduced serial buffer size in Arduino 1.0 has been causing many failures in ArduinoISP.

Does that impact westfw's optiloader as well?

Or does that run pretty independently of the new Serial.print changes?

I believe that I read in the developers archives that they have fixed that for the upcoming 1.0.1 releasing sometime next month.

Thanx for the replies guys. You guys are awesome. Ima have a look into into burning the bootloader then. I was hoping the chips came pre-bootloaded. O well.

No. It's only a problem with the STK500V1 protocol messages between the PC and the ArduinoISP sketch. The optiloader sketch should still work fine.

Actually you can buy USBasp programmers on ebay for less than the cost of a m328 AVR chip.
(prices start at about $3.00 USD, including shipping to your door.)

Having an ISP programmer allows you to burn the bootloader yourself and never again have to pay the $1-$2 USD markup
for this "convenience".
