Bug Description
Cannot compile programs for new ATtiny devices like ATtiny214/414/814 under avr-gcc(GCC) 5.4.0 from Ubuntu packages.
To work with new devices it is mandatory to use ATMEL packs from http://
According to note in toolchain source source: http://
"
How to use Atmel DFPs with Stanadalone toolchain?
# Download DFP from here (e.g. Atmel.ATmega_
# Unzip .atpack to packs directory (/home/packs/)
# Invoke avr-gcc with additional option -B to tell gcc where to look for device specific information
e.g. avr-gcc -mmcu=atmega328pb -B /home/packs/
"
It works OK for new ATmega devices, but some new ATtiny models has avrxmega3 core and avr-gcc produces this error message:
error: unknown core architecture ‘avrxmega3’ specified with ‘-mmcu=’
Also there is no directory avrxmega3 in /usr/lib/
Status changed to 'Confirmed' because the bug affects multiple users.
