Hello,

so it's my understanding that NK have the avr109 boot loader on them. Is it possible to read this information from the mcu using avrdude somehow? Could I verify what bootloader is on other chips as well? Just curious about all this stuff.

TIA.

AVR109 isn't a specific bootloader, it's an AVR application note published at http://www.atmel.com/Images/doc1644.pdf that describes how someone could implement a bootloader on an Atmega. The NerdKits bootloader is based on the "Foodloader" bootloader published at http://www.lochraster.org/foodloader/?en which is one particular implementation of the protocol described in AVR109.

As far as I know, MCU code should be able to read the contents of program memory in the bootloader area, but there's no standard way to identify bootloader program versions.

Did you know that the printf format string "%.3f" will show three digits after the decimal point? Learn more...
