Hello, Ruby is known to have issues when using the ARM ISA. It's likely a problem with how the system is configured. I would strongly encourage you to not use fs.py, but to write a new Python configuration script from scratch if you need to do unsupported things like ARM + Ruby. Another option is to use Ruby + x86, which is better supported.
As a side note, the option --caches enables the classic caches and --ruby enables Ruby, you should choose only one of them. Additionally, the command line options for cache sizes may or may not work with Ruby depending on the coherence protocol.
