Update to Avrdude 8.1

[MCUdude]

Avrdude 7.0 7.1 7.2 7.3 8.08.1 is a huge improvement over 6.3 and brings lots of new features and bug fixes. Arduino now provides "flavored builds" with statically linked libraries, so boards like Curiosity Nano will work on any OS. You can pull the binaries straight from Github.

Here are a few good ones:

• Support for SerialUPDI. It would be interesting to hear what you think of the implementation.
• Support for arbitrary board rates on macOS. Now 230400 baud is not the upper limit anymore.
• Support for lots of new and fast baud rates for the jtag2updi programmer
• WinUSB driver support for Windows. This means that there's no need for Zadig anymore. Programmers like USBasp and USBtinyISP will just work with Windows.
• Support for the Micronucleus bootloader
• A bunch of new targets supported (including AVR-DD, AVR-EA, AVR-EB, AVR-DU)

Statically linked binaries available here:

For reference, here's my boards manager file:

Hello,

where should Windows users get the 7.0 binary from? 😉
I know the new version only from the current avr-gcc from ZakKemble. From its package I have taken me the files.

Avrdude 7 will not be in 1.5.0, but will be added in a 1.5.x version - the time and effort of testing a new version of an upload tool that I am deemphasizing because of its exemplification of the kitchenskinkism antipattern, and which I'd love to phase out entirely is impossible to justify until a working release with full DD support and the latest hardware serial enhancement is available and peoele aren't screaming that it's broken. ATTinyCore 2.0.0 however will most certainly want this, as it does not use any other upload tool.

but here again half of the information is missing. Where should Windows users get the 7.0 binary from? 😉

Eh, no? I provided a link to the repository where all major OSes' binaries are hosted.

But here you go:
https://github.com/arduino/avrdude-packing/releases/tag/7.0-arduino.3

In the first link it does not go on for me.
The further path /release/tag/... I do not see. Your last link works. Thank you.

For those who are more adventurous, you can try the Windows binary mentioned in this thread. I have tested it with DxCore, megaTinyCore and MegaCoreX. It is based on avrdude git main (with many fixes over 7.0 release).

I have also built Linux and macOS binaries here (32 bitLinux x86, 64bit macOS x86_64).

• Enhance CMake to be able to support static link for Linux and macOS avrdudes/avrdude#1159

You can also try the binaries here. I need to use the 64bit Linux binary under 64bit Linux (no 32bit compatibility layer installed).

I have published avrdude git main snapshot binaries (Linux, macOS and Windows) here for those who are interested to try. git main will lead to 7.1 release.

Now avrdude 7.1 is released (https://github.com/avrdudes/avrdude/releases/tag/v7.1) and on linux (Mint/Ubuntu 64bit) it compiles flawlessly.

For DxCore, it is probably better to wait a bit for the release from https://github.com/arduino/avrdude-packing project.

For those who want to try the 7.1 release binaries for Linux and macOS, you can check out my repo here (only for testing purpose).
