Hi, thank for your quick answer. Yes software are never finalized
Even a beta release can be ok to me in order to start testing the new setup.
I will start with some micro pro 3.3V 8MHz external quartz.
Also if I can help in coding or debugging, happy to help. I spend lot of time programming AVR. Please don't hesitate, ask (PM).
In any case up to you to decide when starting publishing the first release.
Thank for your job and looking forward to test the bootloader
