I tried 17 last night and I have had two problems with it.
- In the Board menu each board is reported twice and there is a tick beside each. Selecting a different board results in that being ticked plus the original choice being ticked.
- ... single pin port definitions (only indirectly referred to in the library) like PB6 do not appear in the core as they did in earlier versions. Is there a work round for this?
Those port defines are in iomx8.h (or iomx0_1.h for the mega) which is included by io168.h / io328.h (or io1280.h)
They work for me .
Can't comment on the boards problem, it works ok on my Windows box
