Hi All,
When using the 2.x IDE you'll notice that there is no option for Board: Nano(old bootloader) anymore and selecting Nano does not work (Upload errors):
I stumbled into this problem recently and found out that when installing the 'Atmel AVR Xplained-minis board collection over the boardmanager, I could select a new 'Atmel atmega328p Xplained mini' board that works with boards that previously in older IDE's needed the 'old bootloader' option.
I hope this is helpfull for anyone with the same problem.
I have this problem and this solution works fine on my mac computer - Thank you!
Unfortunately, I don't have the "Processor" menu option on the old windows machines that I am using with my class. IDE is 2.2.1.
How else can I connect my older Nanos to these machines?
The interesting error is in the output window of your screenshot. Can you copy the full content (right click in the output window, copy all) and paste it here using code tags.
If this is a fresh install, it's strange that you can select Nano but that you do not have the processor option. It would indicate a corrupt installation.
From the IDE, I would downgrade the AVR board package and see if that solves the issue. If yes, upgrade again to the latest board package. Before doing that, clean out the logfiles.
On my Windows system, log files are in C:\Users\yourUsername\AppData\Roaming\Arduino IDE.
Close the IDE, delete the logfiles (except the last one as it might contain relevant information related to your error; just rename that one).
Next start the IDE, downgrade / upgrade and let us hear if it solved the issue. If not, post the last log; it should not be to big so please post it inline (using code tags) if possible.
After that it will probably up to the Arduino team members here to assist.
