Error burning bootloader to A-star 328PB

Hi. First and foremost, thanks for developing awesome support for the 328PB chip.

I am using Arduino 1.8.8 to burn bootloader onto 328PB.
Tools:
Board: “Pololu A-Star 328PB”
Version: 3V, 8Mhz
Programmer: “AVRISP mkII for Pololu A-Star 328PB”

As you can see in the output below, In several places it says writing failed, and a warning that the fuse values are wrong. I can still upload sketches afterwards however (I don’t have a serial connection in my application and “upload using programmer”), so it seems that the fuses have been written. I’m just concerned that the appropriate values have been written.

Have you seen this before and do you think I have a problem? Thanks.

Hello.

What AVR programmer are you using and which version of the A-Star 328PB are you trying to program?

- Amanda

Hi Amanda

These are the options I select under Tools in Arduino IDE:
Board: “Pololu A-Star 328PB”
Version: 3V, 8Mhz
Programmer: “AVRISP mkII for Pololu A-Star 328PB”

I am programming with an AVRISP mkII.

The output shows a problem burning the lock bits, but I’m guessing that they get burned correctly anyway. According to the data sheet the unused bits 7 and 6 are ones by default, so I don’t know why the output says they should be zeros.

Are you actually using a Pololu A-Star 328PB Micro 3V, 8Mhz board?

- Amanda

Hi Amanda

No, I’m programming a factory fresh 328PB

Hello.

We have seen error messages about unused lock bits like that before, and I do not think you have a problem.

–David

Thanks Amanda and David

Love your work, Cheers

Matt.
