Lines 81 to 82 in dec3edd

lock_bits = board.get("bootloader.lock_bits", "0x0F")
unlock_bits = board.get("bootloader.unlock_bits", "0x3F")

Refer to thread https://community.platformio.org/t/avrdude-warning-on-burn-bootloader-with-pio-standard-setting/19227

Solution: modify script this way, please.

lock_bits = board.get("bootloader.lock_bits", "0xCF")
unlock_bits = board.get("bootloader.unlock_bits", "0xEF")
