The talks are recorded and put on YouTube but I do not believe any of
the workshops were recorded.

No on-board storage, you have the write an image to the microSD card..

Using etcher.io

and give it another go.. (don't edit the microSD before you try to boot with it)

[beagleboard] RE: Serial Communication Via XBee, BBB, and AT Commands/Yea Boy!

[Mala Dies]

Hello,

I am following along in a book, "The Hands-on XBee Lab Manual" by Titus. If 
you are a newcomer to XBee and the BBB, get w/ me on this project. Purchase 
the book and we can rewind and retrieve on BBB, XBee ideas, and w/ AT 
Commands.

Seth

P.S. If you are experienced in XBee and serial/UART communication, jump on 
in. There is no reason to just make this entire forum full of our 
complaints or issues. We can use this forum as a discussion board, too. So, 
anyway. Please contact me or leave a message to this post in the methods 
you use to perform serial communications w/ your XBee and the BBB. Yea boy! 
Digi International has a ton of free resources too. You can find them at 
digi.com. So, get a BBB, a XBee, and an adapter board. Then, we can 
serialize communications to the advancement of our forum. Oh and see 
here: http://www.mathsisfun.com/binary-decimal-hexadecimal-converter.html. 
If you need to convert, there is a free resource.

Love this gadget. Just wish it had wifi. Would have made a great companion 
computer for Ardupilot. And,  given the proper capes, it might be a better 
flight controller than bbbmini. If there is enough IO exposed.

You're welcome to use the image or Fritzing sketch here [1].  The part 
itself is in the bin here [2], modeled after an eBay part here [3].

Thanks for the info.  This works perfectly for me.

[beagleboard] Beaglebone wireless not recognized by the pc

[liuyangedward]

Hi,

I'm relatively new to the BBB. My BBB wireless suddenly lost connection to 
my PC. Both my Windows10 and Linux can't see BBB connected to my PC as if 
nothing is connected (for example that's what I found in device manager ). 
To put it in another way, BBB doesn't appear as a USB drive and I can't ssh 
to 192.168.7.2. I've tried this on different PC, different OS and with 
different cables.

After I power it on via USB, the 'Power' light is on and USR0 is flashing. 
I guess the board is still working but it can't talk to PC via USB?? Does 
anyone have any thought on this? Thanks!

Regards
Edward

Is the inner pin is the positive or negative pin?
What is the diameter of the jack? I guess its kind of a form factor standard...

Used to be you could set mac address via env ethaddr in uboot. Does this
still work or via device tree? Seems like the kernel driver would support

Hi,

Is is possible to run multiple ros nodes in BeagleBone blue?   ( Two nodes 
running at two different frequencies)

How to initialize the beaglebone using rc_initialze for multiple nodes?

Re: [beagleboard] Re: BBB not powering on

[Graham Haddock]

All of your description points at a power supply problem.
If the USB power, even for a millisecond, drops below 4.5 Volts AT THE BBB,
the PMIC (Power Management IC) will shutdown.
If you have a computer with a USB port on the low side of the USB Voltage
range (4.5 to 5.5 Volts) then what you describe happens.
So that you have some margin in the system, you should hold the power AT
THE BBB between 4.75 and 5.25 Volts, even with heavy loads of booting or
updating.

If you put an oscilloscope on the power connector of the BBB, you should be
able to see what is happening.

So can we configure the MAC on the ENC? The MAC address is fetched using 
am335x_evm.sh in /opt/scripts. Seems like it could be modified for if an 
adapter is detected in the kernel. 

Aside, u-boot configures the on-board MII because the code was difficult to cut

Correct, neither the ENC28 nor the WIZNET based modules have a
built-in mac address (no eeprom on the module). So it's kinda-random
on every bootup..

Does anyone know if the sessions will be recorded and then posted online at 
some point like with the ELC?

Thanks! jeff

I have noticed that both of my PocketBeagles have unique MACs that do not 
move with the SD card when connecting via USB.  (I tried switching the 
cards between PBs and the MACs stay with the boards.  Could it be something 
in the onboard flash?

[beagleboard] Re: BBB not powering on

[Marco Thome]

Thing is that I'm using only the provided USB cable. What troubles me is 
that the board turns on when I'm using a power adapter (DC jack), but it 
dies as soon as I connect it to the computer with an USB cable.

[beagleboard] USB client port usage with android tablet

[nik600]

Dear all

is possible to use the mini USB port on the BBB REV.C to communicate with a 
tablet via TCP/IP ?

If i connect the USB to my ubuntu laptop i see that the g_ether module is 
loaded and a new ethx device is created, allowing me to connect to the BBB 
on 192.168.7.2.

Is possible to do the same connecting the BBB and a tablet running android 
4.4.2 ?

What features should the tablet support?

Thanks

Re: [beagleboard] Restoring MLO and uboot to eMMC and microSD

['Luther Goh Lu Feng' via BeagleBoard]

I have a BBB which has the eMMC flashed from the microSD card using the 
flasher script. Therefore, the MLO and the u-boot should be idenitical.

Referencing the eewiki page[1]I backed up the MLO from the eMMC and the 
microSD:

sudo dd if=/dev/mmcblk0 of=./mmcblk0_MLO count=1 seek=1 bs=128k
sudo dd if=/dev/mmcblk1 of=./mmcblk1_MLO count=1 seek=1 bs=128k

The shasums are however different:

debian@beaglebone:~$ sha256sum mmcblk0_MLO
493f8723705c73c3383898658ce2b1855bbca219825198d2a23b115ce30a4ada  
mmcblk0_MLO
debian@beaglebone:~$ sha256sum mmcblk1_MLO
51d7b68ec8eac56f6d04371c77885332e9eedc7c5434350750ba58f51e86fd56  
mmcblk1_MLO

Am I backing up the MLO correctly?
