| Apr 1, 2014 at 6:08 | comment | added | Ricardo | Tried it and it worked great! Well, the Uno didn't like the optiboot running on 56200 bps (not sure why), but the Severino and my custom boards with serial FTDI-like programming headers all worked. I also couldn't compile the optiboot slower than that (tried 19200) because other compile errors, but that's ok. I used Arduino IDE 1.0.5 and followed the instructions on .\hardware\arduino\bootloaders\optiboot\README.TXT and didn't have to install anything beyond the IDE. Nice!! | |
