Which "debug USB cable" do you mean? If you mean you're connecting a USB cable from your laptop to the mini-USB connector on the board (like you would do with the old BeagleBone), that won't work. The new BBBlack no longer has the built-in serial-to-USB adapter. You'll need something like http://www.adafruit.com/products/954 to get a working serial console for the BB Black. (Just look carefully at the picture on that web page to see how to connect it.) Of course, SSH is also an option=85 ;-) Tim On May 9, 2013, at 6:47 PM, hiren panchasara wrote: > Hi list, >=20 > 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. >=20 > Now, >=20 > After powering up I connected the debug USB cable from BB to my laptop > (running HEAD). >=20 > dmesg shows: >=20 > 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 >=20 > /dev shows following new entries: >=20 > 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 >=20 > Trying to connecting to it: >=20 > % sudo cu -l /dev/cuaU0 > Connected >=20 > Its stays stuck there without doing anything.
