Im attempting to use a jtag3 with avarice but keep running into the issue that the program just closes on me without any error and doesnt start a GDB server.

~ $ avarice --jtag /dev/bus/usb/001/004 -3 -d -P atmega16 :4242
AVaRICE version 2.14svn20200906, Jun 17 2024 14:14:27

Defaulting JTAG bitrate to 250 kHz.

Im running Raspberry Pi OS 12 (bookworm) on kernel 6.6.31 with libusb 0.1.12.

Mhm, sadly not an error message to go on. Is it possible that you compile avarice yourself with debug flags (-Og -ggdb3) and use gdb to execute avarice? Maybe that'll give you a stacktrace or an indication.
