You should also post your code that causes this... but...

Try un-install and re-install your IDE.

sterretje · January 16, 2025, 6:45am

You don't have an upload problem and hence your topic has been moved to a more suitable location on the forum.

Instead of re-installing the IDE, I would use the board manager to downgrade the AVR board package from version 1.8.6 to 1.8.3 (or basically any older version), test and next upgrade the AVR board package to 1.8.6 again.

avrdude done.  Thank you.

It worked, but now I got this problem.

van_der_decken · January 17, 2025, 7:53pm

Have you done a forum search for avrdude: ser_open(): can't set com-state and read any of the many topics on the subject?

gcjr · January 17, 2025, 7:54pm

what port is active under Tools->Port?

fabiovalandro · January 17, 2025, 7:55pm

Gonna take a look!

fabiovalandro · January 17, 2025, 7:56pm

It is COM5. Apparently is correct.

gcjr · January 17, 2025, 8:04pm

if you unplug you board, does com5 still appear under Tools->Port

fabiovalandro · January 17, 2025, 8:05pm

No.

gcjr · January 17, 2025, 8:50pm

then com5 does appear to be the correct port
