With you.

With you.

Ah thank you, was going to look up minicom after you told me, but I
didn't know I needed it or even that it existed until you just told
me. Are there any other steps other that running `./versa_ecp5.py
--fpga ulx3s85f --load` with minicom running in a separate terminal?

By the way am stuck struggling trying to get minicom working, get this
error `minicom: cannot open /dev/modem: No such file or directory` and
tryint `minicom -D /dev/ttyUSB0` like is suggested when I try to look
this up also fails saying `cannot open /dev/ttyUSB0`.. but it seems
like it should work becuase this is the output of demesg | grep tty
`[938169.823961] usb 1-4: FTDI USB Serial Device converter now
attached to ttyUSB0`.

Is there some standard way of doing this that I'm failing to find in my search?
