I just got my brand new HiFive 1 and fired it up first time today. I found that it creates two logical USB ports (/dev/ttyUSB0 and /dev/ttyUSB1 under Linux and two successive COM ports under Windows). The documentation says to use the one with the higher number to connect to a terminal, which works just fine on both platforms. But what is the other one for? Couldn’t find it in the Getting Started manual, and the only other manual I found was on the FE310-G000 RISC V chip.
- Obviously, what is the other port for?
- Is it guaranteed to be the higher port number on Windows too that I should use for communication?
- Where can I find information like that (other than bothering you)?
Any help will be highly appreciated.
