JeeNodes, Windows, Optiboot
Posted: Wed Dec 21, 2011 2:20 pm
We have had some JeeLinks, JeeUSBs and JeeNode SMDs that refuse to upload under Windows 7 when using the Optiboot bootloader. Optiboot has shipped on those boards for about four months now.
If you have one of those boards, AND are using Windows 7 and are having problems, AND have hardware to do so (whew)
It is probably a good idea to update to Arduino 1.0 and to update your bootloader to the newer Optiboot version (4.4) that is included with the Arduino 1.0 release to see if solves your upload problems. Of course you are also welcome to ditch Optiboot entirely and go back to, what we found was, the entirely trouble-free Duemilanove bootloader.
If uploads seem to be working then I would say to stick with the bootloader that came on your board.
We tested a board in the shop with Windows 7 and it seemed to upload fine with the new Optiboot4.4. We are also looking for user feedback on whether Windows users still have upload issues. Both Modern Device and JeeLabs are mostly Mac shops ( we have some aging Linux and Windows machines too) so we would like to get some user reports with various models of newer Windows machines. (The ones that seem to be giving us headaches right now).
