Is there any chance to support the Microchip AVR ATtiny202/402 CPUs?

Since AVR-GCC 8, the new tiny are supported: https://gcc.gnu.org/gcc-8/changes.html
If I do a `find /usr/local/Cellar/avr-gcc -iname "*attiny817*"` I do get the following:
```

After updating to 8.4, avr-ld produces this error:

Using Serial.begin() etc:
The TxD pin (PA6) goes high but no data comes out. Same using Serial.swap(1).
I noticed the pinout in one of the comments is wrong for TxD, RxD in

New AVR MCUs contain a list containing all interrupts, similar to the following (`attiny412.atdf`):

I'm planning to make a 12V version of this programmer. This will allow users to program chips that's had their UPDI line turned into a GPIO pin.
This version will be physically larger than the non-…

Hi,
Today after I got a linker error on the most recent version of avr-gcc I tried an older version, 5.5.0, and, since it is the same version some of my colleagues are using on other OS I would lik…

I'm able to burn a bootloader to an ATMEGA4809 (40 pin DIP) using jtag2updi, but when I try to upload a sketch I get the subject error:

A support of the MegaCoreX will helpful because there are other boards with MegaAvr0 chips,
(Curiosity Nano, ATmega4809 Xplained Pro ...) which are not supported by Arduino directly.

I have some ATtiny202 around to play with - and some 'micro pro' with 32U4 on. So I thought to use ElTangas jtag2updi to program those.
He gave me the tip to have a look at the ATmega4809 with SAMD…
