Hi Given that the arduino Uno and arduino Nano have the same H.W., I am wondering whether it is possible to install Uno's bootloader "optiboot" on Nano, since Nano's bootloader has problem with the watchdog timer while Uno works just fine with it. I have seen many posts that talk about installing the device's default bootloader (i.e., optiboot for uno). But how about optiboot on Nano or promini? any hidden stuff that I should account for, any ideas, concerns, notes will be highly appreciated.
Also a final note, why the Nano and Promini are not using the optiboot as their bootloader? it seems to me better than what they are using. Any clarification on that?
Thx in advance. Mike
