Arduino-cli: Can't compile for Nano

[nkieffer]

Unable to compile for Nano. The arduino:avr core is installed. I've been able to compile for other boards included in the arduino:avr core.

Sketch uses 2158 bytes (6%) of program storage space. Maximum is 32256 bytes.

Global variables use 52 bytes (2%) of dynamic memory, leaving 1996 bytes for local variables. Maximum is 2048 bytes.

for the new bootloader, the fqbn is "arduino:avr:nano:cpu=atmega328".
but I dont know the option for the old bootloader.

[nkieffer]

Using arduino:avr:nano:cpu=atmega328 as the fqbn worked for me.

for the old bootloader, the fqbn is "arduino:avr:nano:cpu=atmega328pld".

for the old bootloader, the fqbn is "arduino:avr:nano:cpu=atmega328pld".

you mean old, not pld :)

I came to create a new issue about the Nano with the "old" bootloader and found it here. Thank you!

The correct FQBN is: arduino:avr:nano:cpu=atmega328old

for the old bootloader, the fqbn is "arduino:avr:nano:cpu=atmega328pld".

In case someone finds this (like I did). It's a typo, the correct fqbn is arduino:avr:nano:cpu=atmega328old.
