I wrote some UPDATES above.
Though now it appears I'm confused about UNO R3 and it's bootloader
optiloader is used to reprogram an arduino after which the arduino
must be reprogrammed as it's now programmed to be, a bootloader ONLY programmer!
as a bootloader ONLY programmer it will will program a blank 328 that's on a breadboard, or homemade shield ... or in a second arduino???
optiboot is the new boot code which is found in the UNO R3 right?
are they one and the same OR different?
ie. is the bootloader that optiloader ups the same as what's in an UNO R3 ??
And secondly, thank you for reading, I'm also trying to stumble across info as to whether
the various? bootloaders affect what software can be used to upload sketches
use for programming. specifically, would like to be atmel software compatible.
Sorry for not getting it.
won't be long now i hope!
QUOTED:
Optiloader is a sketch designed for bulk upgrading of Arduino board
bootloaders using another Arduino as a device programmer.
THIS IS the regular R3 bootloader that it programs to a blank 328 correct?
optiboot is what we end up with on the once blank 328?
Or is it some other bootloader?
WHEW: nutty or what. I figured it out. Or someone did!
Optiloader is a sketch designed for bulk upgrading of Arduino board
bootloaders using another Arduino as a device programmer. It stores
multiple copies of the optiboot bootloader in program flash memory.
