I've searched through Optiboot threads here at Freaks and I've looked through the GitHub repository, without success.
Here is the situation. Suppose that I actually sell some products and belatedly discover that a firmware update is needed. Its no real problem to distribute hex or similar files. But, I would hate to have to ask a biologist or a forester to install and run the Arduino IDE in order to have a way to pump stuff into Optiboot.
Will AVRdude do it? Or is there some other distributable tool? I would probably put a cross-platform wrapper around around it so that all the user has to do is hook up a USB cable, run the wrapper and point it to the new file, the wrapper taking care of all the command line details.
So, what do folks use with Optiboot at the host end of things?
As an aside, can an Optiboot target bootload system be run from within AS7?
