Warning about FUSE after burning the pololu A-Star 328PB bootloader

The burning was ok, and I can download my applications and they work as they should be. But I am always getting the below warning during the burning. Should I modify the value for the fuse in the bootloader hex. as avrdude is suggesting?

avrdude: WARNING: invalid value for unused bits in fuse “lock”, should be set to 1 according to datasheet
This behaviour is deprecated and will result in an error in future version
You probably want to use 0x0f instead of 0xcf (double check with your datasheet first).
avrdude: 1 bytes of lock verified

Best regards


We have seen error messages about unused lock bits like that before, and I do not think you have a problem. In general it probably isn’t worth trying to modify fuse values unless you’re actually having some problems with it.
