Update toolchain/Atmel packs

[MCUdude]

Atmel/Microchip has just released a new pack for ATmega devices; 1.4.346. This fixes some naming errors I've stumbled across earlier when working with the CCL peripherals. The latest release also fixes incorrect vector tables for ATmega808/809, and error I found back in october without knowing precisely what caused it.

There's a whole thread over at AVRfreaks about the vector table issue if you want to read more. I would be very grateful if you could apply this patch 🙂

@facchinm is this something you can do? The current version Arduino IDE uses also has some copy/paste errors in the iom4809.h (and others) related to the CCL functionality.

I just rebuilt the toolchain with latest packs for both atmega and attiny.
The toolchain is available to be tested as 7.3.0-atmel3.6.1-arduino6 by adding http:https://downloads.arduino.cc/packages/package_megaavr_index.json to Additional json.
It will prompt to install the fake 1.9.9 version of megaAVR core, so the toolchain will be downloaded as a dependency.
@MCUdude let me know if it is packaged correctly 😉

I just installed 1.9.9, and it now compiles using

/Users/hans/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino6/bin/avr-gcc

Everything seems good. Thank you!

PS. is there a lot of work to include the new AVR DA pack as well? 🙂 That new hardware looks even more hardware, and I'd love to play around with it in Arduino IDE!

[facchinm]

Not a lot of work but the procedure is a bit convoluted due to the atpacks license 🙂
If you want to try, copying the build script from https://github.com/arduino/toolchain-avr/blob/staging/atpack.tiny.build.bash and modifying it should ease the procedure

I looked through the atpack, but couldn't find any references to a license. Would you like to point me towards it?

The AVR128DA48 looks like a killer chip, and would be perfect for a "Pro" Nano Every!

[facchinm]

Eheh the license is the one you must accept when downloading the atpack (so there's no easy+legal way to bypass it and the files must be copied manually in the toolchain build folder).
AVR128DA48 looks cool btw 😉 Still no native USB unfortunately.

Sorry for barging in, @facchinm ... But, how could we make it easier to get the atpack..? The intention of the pack server was never to be something user facing, just a cmsis compliant repository (I.e the web UI is just something similar to the Keil site).

Hit me up somewhere if you want to talk 😄

This is a very old issue but now there are Arduino 3rd party core to support UPDI AVR chips.

https://github.com/MCUdude/MegaCoreX (you can use Nano Every using this one)
https://github.com/SpenceKonde/DxCore (you can use AVR DA/DB/DD parts)
https://github.com/SpenceKonde/megaTinyCore (you can use UPDI Tiny AVR0/1/2 chips)
