I've raised an issue on google code although not sure if it is properly tracked.
As a consequence I've tried first to get optiboot from here...
Who can replace a bootloader in the repository and accept a library code change?
Or rather - what's the correct process to do it (as it seems issues tab is used just to track internal code changes)?
"Properly tracked"? What does that mean?
I believe Tom Carpenter is the original author of the version included in the Tiny Core...https://github.com/TCWORLD/ATTinyCorehttps://github.com/TCWORLD/ATTinyCore/tree/master/tiny
The Issues list is my (partial) work list. Creating an entry there is a good start.Discussing changes here is a good choice.
Any suggestion to my second question? So far I didn't find any better way rather than creating variants folder, moving default build_options to standard variant and adding that standard variant to all non-optiboot boards, and creating custom variant for optiboot one.
How do I submit changes btw? Series of patches (aka lklm) or pull request (aka github)?
