Description Georg-Johann Lay 2016-11-09 13:54:30 UTC
avr-mcus.def currenly lists at43usb320 as belonging to avr31.  This is not correct because the device can only handle 64 KiB of (external) program memory but avr31 is for devices with 128 KiB (supports ELPM which is not supported by at43usb320).

As the data sheet does not mention the exact instruction set supported, it's unclear if avr3 is the correct multilib (likely) or avr35 (if MOVW) or even avr5 (of MUL).
Comment 1 Georg-Johann Lay 2024-07-06 19:51:54 UTC
There's not enough information about the MCU in order to decide how to proceed.
