Hi list,

I've built img using crotchet scripts (great work!) a few days back
from HEAD and followed instructions at
https://wiki.freebsd.org/FreeBSD/arm/BeagleBoneBlack.

Now,

After powering up I connected the debug USB cable from BB to my laptop
(running HEAD).

dmesg shows:

ugen0.5: <Texas Instruments> at usbus0
umodem0: <Texas Instruments AM335x USB, class 2/0, rev 2.00/0.00, addr
5> on usbus0
umodem0: data interface 1, has no CM over data, has no break

/dev shows following new entries:

crw-rw----  1 uucp    dialer     0x97 May  9 18:13 cuaU0
crw-rw----  1 uucp    dialer     0x98 May  9 18:13 cuaU0.init
crw-rw----  1 uucp    dialer     0x99 May  9 18:13 cuaU0.lock
crw-------  1 root    wheel      0x94 May  9 18:13 ttyU0
crw-------  1 root    wheel      0x95 May  9 18:13 ttyU0.init
crw-------  1 root    wheel      0x96 May  9 18:13 ttyU0.lock
lrwxr-xr-x  1 root    wheel        9B May  9 18:13 ugen0.5 -> usb/0.5.0
crw-rw-rw-  1 root    wheel       0xe May  9 18:11 null
crw-------  1 root    wheel      0x1b May  9 18:10 bpf

Trying to connecting to it:

% sudo cu -l /dev/cuaU0
Connected

Its stays stuck there without doing anything. Same with ttyU0. Is that
not how you connect to this thing?

In my quest of understanding /dev entries, I found: ttyU0 is actual
tty device and cuaU0 is a callback device?

Also,  I am not getting those blue usb lights turned on. Not sure if
that means something.

I am sure I must be doing something really silly. Any help would be great.

cheers,
Hiren
