Although Intel (aka the Altera bit) are claiming current version of their Quartus fpga build software is the last one the will support the nios2. They are expecting everyone to move to a risc-v soft cpu instead. We aren't happy about that, I doubt some of the big telco's are either - I believe some mobile base stations have fpga with a lot of nios2 in them - almost certainly running with a few kB of code and data memory and running small control tasks. If you want to run Linux, find an fpga with an ARM core. There are some solutions - like writing a compatible soft cpu.
