Sorry, but PlatformIO hasn't been updated to use Urboot yet.
I've done all the work, I'll just have to do a bit more testing before this PR can merged. Meanwhile, you can burn the bootloader using Arduino IDE, and in platformio.ini, use upload_protocol = urclock instead of arduino.

Sorry, that was a late night typo. It was supposed to be now instead of not 😅
You can not set the correct fuses, flash the Urboot bootloader and upload using PlatformIO.

No problem! I understood about Urboot after reading the PR and related issues you showed me. Very nice improvements! Until these are released in the near future, I will continue to work with the Arduino IDE.
Thanks for the clear explanation.

The PlatformIO MiniCore template has now been updated with Utboot support:

(Sorry I don't think I understand your one sentence correctly...)
So does that mean that even with the latest version, I can't upload code with PlatformIO?
Maybe if I wrote the bootloader using 3.0.0 in the Arduino IDE (the first way in this issue),
I would have written a bootloader for optiboot version...?
Do I need to write the bootloader for urboot again with PlatformIO with the config value and the following command?
board_bootloader.type = urboot
pio run -t bootloader -e fuses_bootloaderfrom minicore.

Working in the middle of the night is what fails :)
Good news, I successfully wrote it in my environment!
- Connected ATMEL ICE and wrote the bootloader with
pio run -t bootloader -e fuses_bootloader. - after that, I uploaded the code as usual, and it succeeded.
Only one problem remained. That is that the code upload speed only worked at 38400 bps.
However, I assume this was due to the use of the built-in clock generator.
Also, the size of the upload code was small and I did not experience any problem with the write speed for me, so I do not see the need to do anything further.
I'll leave the record here in case it might be of help to others.
This is the platform.ini at this time:
