Arduino bootloader-programmed chip

by allenn on Fri Dec 28, 2018 10:45 am

I purchased 3 Arduino bootloader-programmed chips Atmega 328P). None function in the Arduino Uno. They will not run a simple blink sketch. The original chip will run the blink sketch. As I understand it, this is how I am to communicate with Adafruit support.

When you power-up the UNO with the chip installed, is there any LED activity on the board?

Is the one next to the 'L' steady on, or does it flash a few times?

When the board is powered up pin 13's on board LED is illuminated. When I check the voltage of pin 13 I am reading only .15. The chip does not accept programs.

It seems to flash about 4 times, then it is steady on (at power up).

OK. It sounds like the bootloader is active. When you try to upload your blink program, what is the error output from the Arduino IDE? Is there any LED activity when you attempt the upload?

Pin 13 'L' LED flashes 3 times and then remains on. Very rarely does TX or RX flash, when they do it is a quick dull flash.

The problem is the board type selection. The "Adaboot" bootloader programmed onto those chips is compatible with the Duemilanove bootloader. So you need to select "DUEMILANOVE with ATMEGA328" as your board type in the Arduino IDE. All other capabilities are identical with the UNO.
