Re: [avr-chat] Re: which bootloader ?

[Bernard Fouché]

Well, the message appeared 3 times :)

BTW avrdude goal is to allow programming a chip without using a 
bootloader. And a bootloader is used to program a chip without a tool 
like avrdude. A bootloader is designed to get the data to flash from a 
media that suits your particular needs (serial link, CAN bus, ethernet, 
SPI, etc). There are some bootloader examples on avrfreaks 
(http://www.avrfreaks.net) and avr-libc has functions and explanations 
to allow you to write your own bootloader. Bootloader memory is usually 
rather small on AVR targets (8k max), so there is no generic bootloader 
like RedBoot for eCos on AVR targets. (someone correct me if I'm wrong)

I guess that's why your question about 'a bootloader supported with 
avrdude' gave not much traffic on the list.
