Nano with Optiboot: maximum sketch size and fuses not updated

[oqibidipo]

If I am not mistaken, these

nano.menu.cpu.atmega328.upload.maximum_size=30720
nano.menu.cpu.atmega328.bootloader.high_fuses=0xDA

should be

nano.menu.cpu.atmega328.upload.maximum_size=32256
nano.menu.cpu.atmega328.bootloader.high_fuses=0xFD

Hi @oqibidipo , you are right, but the boards in production have been flashed with the old fuse setting, making the bootloader partition larger than needed (see arduino/Arduino@1cf34c8#commitcomment-27651798). So we can't change the maximum sketch size parameter without affecting the functionality on these boards, sorry.

Wouldn't adding another entry for the Nano have been a better solution for this? If the production units are still being incorrectly flashed, call it (New Bootloader - Production) and (New Bootloader - Max Flash) or something like that. As it seems a bit silly to have to use the Arduino Uno setting for an Arduino Nano to get the proper bootloader partition size and corresponding maximum sketch size! 😆 😆
