Hi @amarotica, thanks for the PR. It looks good overall, but I’d also like to ask @MCUdude to take a look since he originally contributed support for programming fuses for DxCore targets. |

I'll try to go though and look for any errors. But IMO @amarotica should add all AVR-DD targets, not just two of them. They are all pretty much identical, except for the memory size and pin count. |

Summary
AVR16DD20andAVR16DD32board manifests for DxCorefuses/bootloadertargets use safe DD-family valuesWhy
platform-atmelmegaavralready includes DxCore support and AVR64DD board manifests, but AVR16DD20/32 are still missing.Validation
I validated the added board manifests by building simple Arduino sketches locally for both:
AVR16DD20AVR16DD32I also verified the generated AVR-DD fuse bytes for the typical no-bootloader UPDI setup now match the intended DxCore values.
Remaining blocker
Full stock support still needs a
platformio/toolchain-atmelavrupdate to addavr16dd20/avr16dd32device specs and headers. Without that package update, these new board definitions still require an external DD-capable AVR toolchain.
