Hi,
I'm using FreeBSD on various hardware including some Beaglebone blacks, which is great and runs smoothly.
A BBB sports four UARTs, spread over the it's expansion port headers P8 and P9, one of which via pins GPIO0_30 and GPIO0_31 on header P9. Unfortunately (or maybe because I'm too unexperienced) this Serial4 has no corresponding device under /dev to let me use it with e.g. minicom or ntpd.
So, my question is: how do I create serial devices to hardware ports on that computer? In FreeBSD Handbook there are a few chapters covering serial port setup. They care about normal PC hardware all the time. I got some forwarding pointers though, stty(1) and /etc/ttys to name two. If I grep uart in /var/run/dmesg.boot, I only see one (uart0) listed. Why's that? Where are the remaining three?
Can anyone please push me in the right direction?
Thanks in advance!
