slightly embarrassed to ask a couple simple questions about just
getting started with playing with a bone A6, as i'm not sure how
networking is supposed to work out of the box and i can't seem to
match what the startup instructions suggest. (a pointer to a page
with an explanation will work just fine.)
currently running 64-bit ubuntu 12.04 (fully updated), and the SD
card i got with the bone reads "6-18-12", so that seems current
enough.
if i use just the USB/serial cable to both power and connect, that
works fine -- plugging in the beaglebone loads modules usbserial and
usb_storage, then creates /dev/ttyUSB[12], and i can connect with:
$ screen /dev/ttyUSB1 115200
and i'm in:
Angstrom v2012.05 - Kernel 3.2.18
also, /media/BEAGLE_BONE is now mounted on the host. so all of that
seems fine.
what i can't get to work is the startup scenario using networking.
what host-side config should i have for the bone to automatically
start networking? as i read it, i simply need to have a regular
ethernet cable between the host PC and the bone, yes? am i missing
something obvious? thanks.
Robert,
The Beaglebone uses DHCP to acquire its IP address etc. From what you say you have connected the Beaglebone directly to your PC. Unless you have a DHCP server configured on your PC, it will not work. A more usual configuration would be to connect the Beaglebone Ethernet cable to a hub on your LAN which also serves your PC. The DHCP service being provided for example by a router.
i had assumed as much, but the piece of paper that came with my
beaglebone clearly suggested connecting direct ethernet port to port,
which confused the heck out of me, but i figured, ok, i'll just follow
the instructions and see what happens. i am not at all surprised it
didn't work.

At home I connect my beaglebone to my router. While on vacation, I think I connected my laptop directly to the beaglebone. I believe the instructions you mentioned tell you to unmount or eject the BEAGLE_BONE partition at which point the beaglebone can communicate with your computer. I think when you reject the USB connection (power only), you activate the Ethernet connection.
I too am new to the beaglebone so forgive me if this is wrong or doesn’t help,
I can see why you were confused about the Ethernet connection, then. I think those instructions refer to using the “TI EZ SDK SD” card, not the Angstrom image. I actually never used the card, and ended up overwriting it.
ok, that makes sense since i got my first beaglebone (an A3, i
think) from digi-key, and i guess i still had that paper lying around
when i got a new A6 with an angstrom card.
TI gave us those to throw in the box to promote the TI SDK, but it wasn’t the BeagleBoard.org demo image (another SD card was contained within the tin) and it was only with rev A3 boards. What confused me is this email said A6, so I am still lost as to what paper.
my lack of clarity ... i thought that paper *had* come with one of
my A6's, but it was clearly a leftover from when i had earlier ordered
an A3 from digi-key. so my mistake.
